->''"Sarah, your suspension from lacrosse for excessive force has been lifted, so you're going today... Henry, you have band practice, all right? I cleaned your clarinet. Please don't play with your food in your mouth again. Kim and Jessica, your teacher called and has made a request that you do not correct her in front of the class. Mike, you have show-and-tell today. And please, honey, remember that body parts do not count. Kyle and Nigel, you have a dentist appointment at 3:00, so you're going to work with Dad."''
-->-- Kate Baker (bear in mind this covers barely half the kids)

2003 film starring Creator/SteveMartin about him, his wife and their twelve kids. Count 'em, ''twelve''.

VeryLooselyBasedOnATrueStory, in that there was a [[Literature/CheaperByTheDozen 1948 book]] and 1950 FilmOfTheBook also called ''Cheaper by the Dozen'' which had a family with twelve kids in it. The [[Literature/CheaperByTheDozen original book]] is set in the 1920s and was written by Frank Gilbreth Jr. and Ernestine Gilbreth Carey. That's the only similarity. The Gilbreth children were: Anne, Mary (1906-1912), Ernestine, Martha, Frank Jr., William, Lillian, Frederick, Daniel, John, Robert and Jane. The authors wrote a sequel called ''Belles on Their Toes'' which follows the family after Frank Gilbreth, Sr's death. Mrs. Lillian Gilbreth (the mother) served as an adviser to five American presidents (Hoover, Roosevelt, Eisenhower, Kennedy, and Johnson); she and her husband are part of a permanent exhibit at the Smithsonian Institution. The last surviving child, Frederick, passed away in December of 2015.

Plotwise, the family is happy, but packs up and moves an unspecified distance from a small town into the suburbs of Chicago so the Dad can pick up his dream job coaching his old college [[UsefulNotes/AmericanFootball football]] team. The kids are variously disappointed by this, but grudgingly go along with it anyway. Having left home, the family gets another shock - Mom's gonna get her book published! Mom goes on a book tour, leaving the family in her husband's hands for a few days. HilarityEnsues as total chaos erupts. One kid runs away, the family chases him down (leading to a nice YouAreNotAlone moment), Dad realizes what his job has done to his kids and both he and his wife resolve to put family first.

A generally inoffensive family comedy.

A sequel was released, running with basically the same premise but a different plot, in which the family goes to a lake for a vacation but run into an old rival of Dad's---who has a big family of his own. Naturally, everyone else ends up hitting it off well, which ultimately leads out to some fallout with the fathers and their families, but they make up in time to win a contest. Meanwhile, the oldest daughter gives birth to her first child.

As harmless as the former, but less successful at the box office.

The films play straight pretty much every trope listed under FamilyTropes, SiblingTropes and TheParentTrope. As a result of this and rather poor writing, many audiences disdain them, but they've also gained enough of a following to provide a character page.

----
!!This film provides examples of:

* AbortedArc: Charles's conflict with the city kids in the first film.
* ABoyAndHisX: Beans the frog is Mark's best friend. [[spoiler: The fact that nobody seems to care when he dies is what causes Mark to run away.]]
* AccidentalMisnaming: Tom gets Mark's name wrong twice throughout the film. Both times, Mark corrects him. The second time, Tom corrects himself after getting it wrong.
-->'''Mark''': Have you seen my frog, Dad?
-->'''Tom''': Sorry, Charlie. Nigel. Kyle.
-->'''Mark''': It's Mark.
-->'''Tom''': I knew that.
* ActuallyPrettyFunny: "You soaked his underpants in meat. That is so ''wrong''. Funny! But ''wrong.''"
* AdoptionDiss: Mark's nickname of "Fedex" is used by his siblings to imply this.
* AwLookTheyReallyDoLoveEachOther: None of the Baker kids, especially Sarah, care very much when Mark's frog Beans dies, but when they find out he ran away, they're all shocked and actively take part in the search for him.
** Lorraine and Sarah too have a moment of this, where Mark says when he's reunited with everyone that he figured everyone hated him like Sarah and Lorraine seem to, only for Lorraine to say, "There are times when I'd want to kill Sarah, but I'd kill ''for'' her all the time."
* BigBrotherInstinct: The kids have this for each other. When Jake, Jessica, Mike and Kim find out Mark is being bullied at school, they confront the bullies and give them some LaserGuidedKarma. Subverted in this case though, as Jake is the only member of this group who is older than Mark.
* BigFancyHouse: The Bakers' new home after they move house early on in the film.
* BookEnds: The film starts with Kate listing negative or neutral things the family associates with the number twelve, and the film ends with her listing [[TriumphantReprise positive things]] the family associates with number twelve.
* BrattyHalfpint: Sarah. Especially when she's torturing Lorraine.
* BreakingTheFourthWall: InUniverse. While the Bakers are watching Tom's interview by Fox Sports, he looks into the camera and says, "Go to bed, kids!" Kate turns the TV off and sends the kids to bed.
-->'''Kate''': "OK, you heard the coach."
* CallingTheOldManOut: Tom gets this from Charlie [[spoiler:after Charlie is kicked off the football team due to being bullied.]] At the end of it, Charlie tells Tom that once he graduates, he's leaving.
* ChildHater: Hank. He puts having a family after death and taxes, and outright calls the kids monsters when the two walk in on a fight.
* ChildProdigy: Kim and Jessica are very brainy for their age.
* DespairEventHorizon: After the segment with Oprah is ruined, Kate and Tom have all but stopped talking, the children are all at each other's throats and Mark's beloved frog suddenly dies. And then Mark runs away, fed up with all the fighting and feeling neglected by his family.
%%* EnfanteTerrible: Again, Sarah.
* EstablishingCharacterMoment: As the Shenks are approaching the new Baker house after they've just moved in, Tina reveals herself as a {{Jerkass}} in her first line when she notices the cartons and cups on the dashboard of the Baker van: "Oh, God. They're fast food people."
* ExiledToTheCouch: Implied. Before Mark is revealed by Kate to have run away, Kate tells Tom "Feel free to sleep on the couch". Tom replies "You read my mind", implying he was going to anyway.
* FatalFlaw: Pride is Tom's throughout the film. He moves the family to their new home simply so he can pursue his dream job and look good in front of Shake. He also tells Kate [[TemptingFate he can handle looking after the kids by himself]] when she goes to New York. Cue an OhCrap from him when she tells him she's gone for at least two weeks, and he has to ask Nora for help, which means she has to give up time from her new job. Understandably, Kate is quite angry with Tom when she comes home. And all of this ends up leading to Mark running away. When Tom catches up to him, Mark tells Tom he didn't keep his promise of them becoming a happier and stronger family.
* FoodAndAnimalAttraction: The kids prank the Nora's boyfriend by dipping his underclothes in meat and setting the family dog on him.
* {{Foreshadowing}}: A fairly obvious example in which Tom mentions in the first scene how the family could do with change---of which a lot, of course, ends up happening over the course of the film.
** Early on, when Kate hugs Mark but then gets distracted by Nigel and Kyle wrestling, she looks around for him and sees him cycling away. Mark later snaps and runs away from home when it looks to him like no one cares about him.
** Mark's drawing of the Midland house that he shows to Tom, along with the caption, "My favourite place in the world". When he runs away, he plans on going there, and Tom realizes this thanks to a MeaningfulEcho.
** Mark is seen late in the film tending to Beans and at one point [[PleaseDontLeaveMe begging him not to die]]. Unfortunately, he does die and the argument that follows Sarah's [[KickTheDog rude outburst]] causes Mark to run away.
* FromTheMouthsOfBabes: Nigel and Kyle call Shake a "hot dog" in Shake's first appearance, but only because they'd heard Kate call him that and are probably not aware of what she meant. They also call him a wiener within his earshot as they leave in the same scene, as well as behind his back in a later scene at the Baker house.
* GroinAttack: A variation, as the kids steal Hank's boxers and ''soak them in raw meat'' as he waits for his clothes to be dried, before siccing the dog onto him at the table.
* HappilyMarried: Tom and Kate are still very much in love.
-->'''Tom''': Were you just checking me out?
-->'''Kate''': Maybe I was.
-->'''Tom''': Twelve kids later, and we still got the heat!
* InfantImmortality: Played straight with the Baker kids, averted with Kate's sister, who died as a child in the backstory.
* InNameOnly: The only similarity it has with the book is that there are twelve kids.
* IronicEcho: In the same scene. After Kate tells Tina Mark has run away, Tina says that twelve is just too big a number of kids to have. Kate throws the insult back in her face at the end of the scene.
* ItsAllAboutMe: Hank, who is a self-absorbed model and actor who worries about what the Baker kids will do to him when he and Nora visit (to be honest, though, he is right to worry, after they set his pants on fire). Nora doesn't see him for what he is until Mark runs away and Hank doesn't care at all, preferring to watch a commercial of himself on TV instead of going to help.
** Tom too, to a smaller extent. He moves the family to Chicago when it's obvious none of the kids want to go. Why? So he can pursue his dream job, and says they will be a happier and stronger family as a result. None of the kids buy it [[spoiler:and when Tom catches up to Mark after the latter runs away]], Mark tells Tom he didn't keep his promise to the family because they're not happier than they were.
* {{Jerkass}}:
** Hank ends up being this to a degree. See ItsAllAboutMe.
** Tina as well. It's pretty clear from the off that she doesn't like the Bakers because of how many kids they have and their parenting methods. She also seems a snob that fusses over Dylan and shows no sympathy to Kate when Mark has run away.
* JerkWithAHeartOfGold: Most of the kids, who pull pranks and don't care much when Mark's frog dies, but they still feel bad when he ran away, and so still see him as very much a brother and member of the family.
-->'''Jake''': Without you, we wouldn't be the twelve Bakers any more. We'd be like... eleven.
** Even Tom gets hints of this. He moves the family to Chicago even when none of the kids want to do it, just so he can pursue his dream job and look good in front of Shake (Charlie says later that Shake was a superstar in college, whereas Tom was a loser, while he is CallingTheOldManOut), and becomes something of a workaholic so doesn't see the kids' side when they're either ignored or punished for fighting in school, but of course he still cares very much about the family and Kate and [[spoiler:eventually gives up the coaching job so he can get another job closer to home.]]
* JerkassHasAPoint: The younger kids are clearly shown to be in the wrong to try chasing Hank away with pranks, but they were right that he was unworthy of Nora's time.
* KickTheDog: Sarah telling Mark that no one cares about Beans dying, and then calling him Fedex again. [[RageBreakingPoint Mark shouts at her to stop calling him that]], then goes at her, sparking a fight between all twelve kids and their parents.
* LaserGuidedKarma: The bullies who knocked Mark's glasses off and pulled his hat down over his eyes get their comeuppance when Jake, Mike, Jessica and Kim find out and give them a taste of their own medicine, even if it results in them being punished for it.
* MajorInjuryUnderreaction: Dylan gets a injured by a grown man falling on him. It was still his best birthday ever.
* ManHug: Tom and Shake the first time they're onscreen together, at the start of the scene where Shake pitches his offer to Tom.
* MassiveNumberedSiblings: The Baker clan has, well, a [[ExactlyWhatItSaysOnTheTin dozen]], seven sons (Charlie, Henry, Jake, Mark, Nigel and Kyle) and five daughters (Nora, Lorraine, Sarah, Jessica and Kim).
-->And yet, it doesn't make them a [[IncrediblyLamePun Baker's dozen]].
** According to Kate's voiceover early on, Tom had seven brothers and sisters growing up, and after Kate's sister died, she wished she had seven brothers and sisters as well.
* MeaningfulEcho: Shortly after moving to Chicago, Mark draws a picture of their old house, which is his[[spoiler: "Favorite place in the world"]] After he runs away, the police tell Tom that they searched train and bus stations. He claims that his son wouldn't take a train or a bus. Nora then says that she always wanted to run away to Chicago, which was her[[spoiler: "Favorite place in the world"]]. [[EurekaMoment This makes him realize exactly where Mark has gone]].
* MiddleChildSyndrome: An interesting example combined with OutOfFocus; Henry and Sarah are never shown going to school, while the rest of the kids are.
* MoodWhiplash: Two, involving hugs.
** As Mark is leaving for school at the start and tells Kate he doesn't feel like he fits in the Baker family, Kate tells him he does fit and hugs him, then seconds later gets distracted by Nigel and Kyle wrestling on the lawn.
** After the Oprah segment has to be cancelled, Jessica witnesses Tom tell Kate he was going to sleep on the couch, and asks if Tom and Kate will get a divorce. Tom wordlessly picks her up and hugs her. Then comes a big moment of shock when Kate appears and tells them Mark has run away.
* MsFanservice: Tina.
* MyBelovedSmother: Tina acts this way towards Dylan, who wanted "one perfect child", though it's implied Dylan wanted siblings.
* NeverMyFault: The kids consistently blame their father for their unhappiness and rarely fess up to the chaos they have created at the expense of each other and their parents. To be fair to them, the cause of some of their unhappiness ''is'' Tom's fault, though much of the chaos is squarely down to the kids.
* NoGoodDeedGoesUnpunished: Played with. When Jake, Jessica, Kim and Mike find out Mark is being bullied at school, they give the bullies a dose of LaserGuidedKarma by beating them up. It still gets them punished both by their principal, and then by Tom, who grounds them.
* NoSympathy: Sarah telling Mark no one cares about Beans after Mark tells Kate Beans has died.
** Tina to Kate after Mark has run away, saying that twelve children is too many.
* OhCrap:
** Tom at the beginning during breakfast when he sees Beans in the lamp above the table, with Mark reaching towards it with his net.
** Tom when he tries to grab Dylan hanging from the chandelier, and ends up hanging from it himself.
** Tom has one when Kate calls him from New York to say she will be staying there for longer than expected.
** Henry has a brief moment when he slips on a puddle on Nigel's vomit on the kitchen floor.
** Many people at Dylan's party when the snake the Baker kids got for him escapes from its box.
** Tom and Dylan get one at Dylan's party when Tom is about to land on Dylan after being blown out of the bounce house.
** The chandelier contractor after he falls off the ladder and sees the chandelier about to fall on top of him. [[RunningGag Again]].
* OutOfFocus: Most of the kids aside from Mark.
* PayEvilUntoEvil: The kids' pranks against Hank, who is more {{Jerkass}} than evil, but it still counts.
** Mark's bullies are given a dose of LaserGuidedKarma when Jake, Mike, Jessica and Kim find out what they did to Mark.
* PleaseDontLeaveMe: A variation. Mark is seen late in the film begging Beans not to die. Unfortunately, Beans does die.
* RageBreakingPoint: Mark reaches it after Beans has died.
-->'''Mark:''' Mom, Beans is dead.
-->'''Sarah:''' Nobody cares about your stupid frog right now, Fedex, OK?
-->'''Mark:''' Stop calling me that! ''(attacks her)''
* RealityEnsues: Having twelve kids to divide your attention will mean that ''someone'' gets left out, and that they're hard for one adult to work with on their own.
** Also, you may be defending your brother by beating up his bullies, but that doesn't mean you won't get punished for it. Namely, a trip to the principal's office and then being grounded.
* TheReasonYouSuckSpeech: Lorraine delivers one to her dad towards the middle of the film.
-->'''Lorraine''': You just used your own son as a vomit mop!
** Charles also gives one to him (towards the end of the film).
* RuleOfPool: Invoked by the kids as the first part of the plan to get rid of Hank when he first arrives, resulting him in being tripped with a garden hose and landing in a paddling pool.
* TheRunaway: Mark becomes this after Beans dies and Sarah [[KickTheDog tells him no one cares]].
** During the search for Mark, Nora reveals she ran away from Midland a few times growing up, and considered getting on a train to go to Chicago.
* RunningGag: The family's many attempts to install a new chandelier, usually with it falling atop the contractor.
* ScrewThisImOuttaHere: Kate does this to the book tour in New York when the kids call her after the party scene, and Sarah tells her to come home immediately, because of how bad things are.
** The camera crew setting up for a taping of the family on the Oprah Winfrey show when the family finally collapses into a full blown fight right in front of them. To add to their disbelief, the segment was to be called "One Big Happy Family".
-->'''Cameraman''': ''(Calling Oprah)'' No, you do ''not'' want to come down here. No, it's the ''farthest'' thing from a happy family.
** Charlie tries to do this by saying he wants to go back to Midland. Tom tells him he is not going to walk out on the family. In the end, Charlie implies he will do this once he graduates, after CallingTheOldManOut. He drives off anyway, but returns at some point, as Tom comes to his room later to tell him Mark has run away. Charlie tries to apologize to Tom and say he was out of line, but Tom says he was right.
** Mark does this by running away after Beans dies, saying no one cares about him and it's not until the evening of the same day that anyone notices he has gone.
* ShirtlessScene: Tom Welling's character briefly appears shirtless (unsurprisingly, given how often [[Franchise/{{Superman}} his character]] on ''Series/{{Smallville}}'' did.)
* SingleMindedTwins: Both pairs of twins act quite similar to each other. It's more noticeable with Kyle and Nigel, since they're identical.
* {{Tomboy}}: Sarah.
* TheThreeCertaintiesInLife: Hank notes, "All I'm saying is families are inevitable; they're like death or taxes."
* TriumphantReprise: Kate listing positive things to associate with the number twelve at the end of the film, as opposed to neutral or negative things [[BookEnds as she did at the beginning]].
** Before Kate calls Tom after finding out what has happened while she has been in New York, the scoreboard shows the Stallions lost against a team called the Pythons, when the situation at home seems to be at its nadir. At the end, when Tom gives up his job, the same scoreboard is seen again and this time, the Stallions have won against a team called the Ridgebacks, and shortly after that comes a big family hug on the field.
* TheUnfavorite: Mark, a.k.a. "Fedex", at least in the eyes of his siblings.
* UnwittingInstigatorOfDoom: Mike at Dylan's party. Jake tells him to go get the football they got for Dylan so they can play with it. When he does, he knocks some of the presents over, and the Brazilian mud wiper they also got for him escapes. The [[OhCrap resulting panic]] causes Tom to realize the kids have gone, and to enlist the players to round them up, as well as, in trying to get Sarah, [[ItMakesSenseInContext Tom ending up breaking Dylan's arm by accident]].
** Sarah dishes out a KickTheDog moment to Mark after Beans dies, causing him to lash out in anger. This causes a massive fight that causes the scheduled Oprah segment to have to be cancelled, and causing an upset Mark to run away from home.
* VomitDiscretionShot: Two in the same scene. Nigel sees red sauce on Mike's athletic cup, and vomits on the floor thinking it's blood. Henry comes in and slips on the vomit, causing him to throw up too.
* YouAreGrounded: Tom says this almost word for word to the kids when their poor behavior gets out of hand.
----
!!The sequel provides examples of:

* CallBack: When he gets fed up with Jimmy, Tom asks Sarah if she's still "in touch with [her] dark talents." She sets up the same meat trick she pulled in the first movie.
* DemotedToExtra: Mark. He was ''the'' main character, aside from the parents, in the first movie, but is barely in this one.
* DisasterDominoes: The destruction of the clam bake. It all starts when Mark absentmindedly sets his backpack full of fireworks next to an open flame.
* TheGloriousWarOfSisterlyRivalry: Lorraine and Sarah have entered this even deeper than in the first film.
* ForgottenFallenFriend: Mark never even mentions his frog.
** It could be interpreted as Mark having moved on after losing Beans.
* HiddenDepths: Sarina is initially presented as Jimmy's DumbBlonde trophy wife, but she truly wants to be a good mother to her stepkids. When she sees the wedge that Jimmy's pressuring and obsession with upping Tom is driving between himself and his kids, she sets him straight.
* InstantBirthJustAddWater: Averted. Nora is giving hints all day that she's going into labor. She keeps her mouth shut though, so it won't ruin the contest for the family. [[spoiler: Until her water breaks in the middle of the final event and she finally has to admit she needs to go to the hospital.]] There's still a significant amount of time from then until the delivery, though.
* LotsOfLuggage: When Lorraine shows up at the cabin, Sarah keeps jabbing at her for her huge suitcase. "So is this one just for your makeup?"
* NauticalKnockout: This happens to Tom.
* PutOnABus: All the supporting cast.
* StealthPun: Nora has her baby on ''Labor'' Day.
* TrophyWife: Sarina, Jimmy's new wife of "six wonderful months."
* UglyGuyHotWife: Jimmy Murtaugh and his new trophy wife, Sarina.
* UnluckyExtra: The poor old man in the wheelchair. Every time he is on screen, he somehow gets pushed into the water. You think he would put on his parking brake, or have someone park him in a less precarious spot.
