One baby, often a newborn, is secretly exchanged for another.

May be a living baby for a dead one, the son of a [[BlueBlood rich family]] for the baby of a beggar, or an accidental swap in the hospital nursery. In any case, the problem is that the babies were swapped, and they won't find out until later in life. Usually, in the worst moment. Frequently, the finding ''is'' the worst moment.

Favorite of {{Soap Opera}}s around the world. With all the use this trope has had, you'd think that it would be a DeadHorseTrope by now, but it's [[UndeadHorseTrope still alive and kicking]].

Compare MosesInTheBulrushes and the [[TwinTropes twin specific]] version SeparatedAtBirth.

Someone who [[IJustWantToBeSpecial fantasizes]] they were SwitchedAtBirth has a ChangelingFantasy.

ChangelingTale is an [[OlderThanPrint older]] subtrope involving [[TheFairFolk elves]] [[InvasionOfTheBabySnatchers snatching babies]]. They will often replace it with a {{doppelganger}}. Related to PrinceAndPauper.

* ''Manga/BlackJack'' has the chapter "Switched". A mother is blackmailed by a particularly unpleasant woman, who claims to have seen her switch her baby with another one in the maternity ward shortly after discovering that her son had a rare, most likely terminal condition. Once she can no longer make the payments, the mother allows her blackmailer to accuse her of kidnapping. The key witness is Dr. Black Jack, who [[spoiler:reveals that it's a subversion - he states that he operated on the child, curing his condition, and that the scar on the child is proof that he belongs to his mother. On the way out, he informs the the blackmailer that after the operation, he saw the child's unknowing mother switch the babies... and ''switched them back''.]]
* PlayedForLaughs in ''Manga/DailyLifeWithMonsterGirl''.

The scientist in charge of the SuperSoldier project that created Eve felt guilty about condemning the unborn Eve to life as a lab experiment and had her SwitchedAtBirth with a stillborn child. The parents were initially surprised to see Eve after being told their baby hadn't survived, but quickly decided it wasn't important -- their daughter was alive and that was all that mattered.

* A similar theme is used in the 1988 film ''Film/{{Big Business|1988}}'' with Creator/LillyTomlin and Creator/BetteMidler playing the mismatched sets of twins - each named Rose (Tomlin) and Sadie (Midler) - of a rural working family and a wealthy urban family. Unusually, in the end neither birth nor upbringing turns out to provide the stronger link between the women; instead, urban Rose and country Sadie are {{Wide Eyed Idealist}}s while country Rose and urban Sadie are aggressive and cynical.
* The very same year, French black comedy ''[[ La vie est un long fleuve tranquille]]'' mixed this theme with {{Slobs Versus Snobs}}. On Christmas Eve, as she was rejected by her married OB-GYN lover, a midwife switched two babies born that night, a white-trash girl and a well-bred boy. After a final betrayal, twelve years later, the midwife reveals the ugly truth, and the boy comes to live with his rightful family.

* ''Film/TheOmen1976'' began with an swap between a dead baby and a mysterious newborn.
* The most mind-hurting example is in the 1970 movie ''Film/StartTheRevolutionWithoutMe''. In pre-Revolutionary France, two sets of identical twins are born on the same night and delivered by the same doctor, so there are ''four'' babies. The midwife and doctor can't remember which is which, so they shuffle them a bit so "at least we'll be ''half'' right". They grow up as two sets of fraternal twins, one aristocratic, one revolutionary peasant. Then the French Revolution comes around...
* The Creator/EricIdle[=/=]Creator/RickMoranis vehicle ''Film/SplittingHeirs'' was a pretty straightforward take on this.

Thirty-one years later Tommaso (7) and Daniele (8) meet each other by accident and, after some events, they discover the truth.


[[folder: Literature ]]

* In an obvious nod to ''Film/TheOmen1976'', ''Literature/GoodOmens'' starts with a baby swap that [[SpannerInTheWorks doesn't go quite the way the swappers plan]].
** To be fair, they had to deal with three babies, not two; "a golden-haired male baby we will call Baby A," "a golden-haired male baby we will call Baby B," and "a golden-haired male baby we will call the Adversary, Destroyer of Kings, Angel of the Bottomless Pit, Great Beast that is called Dragon, Prince of This World, Father of Lies, Spawn of Satan, and Lord of Darkness".
* This is part of the plot of Creator/MarkTwain's novel ''Pudd'nhead Wilson'', involving two sons of a white plantation owner, one by his wife and one by a slave woman, being switched at birth by the slave so her son could live a life of privilege. [[spoiler: The titular Wilson finds out ''almost twenty years later'', when he takes the defense of an Italian man (himself a twin) who has been mistakenly accused of murder -- and the slave's son is the culprit. In the end, after Wilson reveals the whole switch to save his client, the slave's son is formally enslaved and sold down the river, and the wife's kid is brought back into the family... but he's a FishOutOfWater and not happy about it.]]
* Creator/PGWodehouse's ''If I Were You''.
* In "Lady Clare," a lengthy poem by Alfred, Lord Tennyson, the titular noblewoman discovers that her nursemaid Alice is actually her biological mother, who had been the nursemaid of the real Lady Clare.

* In Creator/AndreNorton's Literature/WitchWorld novel ''The Jargoon Pard'', Kethan is switched at birth for a woman's daughter, because [[HeirClubForMen only a son can inherit]]. [[spoiler:At the climax, this is revealed to the woman and his parents; they reveal that actually, they knew it for a long time. Kethan nearly [[DarkestHour despairs]] because his purported mother no longer wants him, because she can no longer use him. After the fight, however, his parents eagerly lay claim both to their biological son and the daughter they raised.]]
* The protagonist of Creator/TadWilliams' ''Literature/TheWarOfTheFlowers'' was born in the MagicalLand, but switched at birth for a child from the mundane world in an EquivalentExchange.
* As was the protagonist of Creator/RogerZelazny's ''Madwand''. In the end the two changelings end up making war on each other.
* The fantasy novel Split Heirs involves a royal set of boy/girl triplets, where the girl, and younger boy triplet were supposed to be secretly sent off to be raised by the queens brother, while the firstborn boy was to be raised to be the heir to a warrior kingdom. A mix up occurs, and the girl is raised as a prince, and becomes a fearsome warrior, while one boy becomes a shepherd, and the other a wizard's apprentice. The culture of the story thought that multiple births meant the queen had been unfaithful, which would have meant her execution. Also, a girl would not have been able to inherit the throne, so the queen kept the girl's sex a secret [[spoiler: even to the girl herself.]]
* A lot of baby-shuffling occurs in ''Literature/SeptimusHeap''. [[spoiler: The title character is pronounced dead at birth by the midwife, but she actually steals him and he ends up getting switched with her own son. Meanwhile, Septimus' father finds an abandoned baby girl, and since his wife is known to have been pregnant and they think their baby is dead, they adopt the girl and pretend she's their own daughter.]]
* In Creator/LMMontgomery's ''Literature/AnneOfGreenGables'' series (Anne of Ingleside), a mean little girl convinces one of Anne and Gilbert's twin daughters, Nan, that she was switched at birth with a fisherman's daughter. The girl insists that twins always look alike, and the fact that Nan and her twin Di don't, being fraternal twins, it proves that they were switched at birth. Nan does the honorable thing and tries to switch back, only to be told by the fisherman's wife that her daughter is nearly a year older than she is, and therefore they could not have been switched. Quite relieved, Nan turns to go home and gets caught in a storm before returning safely. Anne and Gilbert are understandably upset.
* At least two instances in ''Literature/ASongOfIceAndFire''. In ''A Feast for Crows'', Mance Rayder's son is switched with Gilly's son in order to prevent Melisandre from taking advantage of his "royal blood" as a sacrifice to R'hllor. ''A Dance with Dragons'' reveals [[spoiler:someone who claims to be Aegon Targaryen and survived his apparent murder due to a baby swap.]]
* ''Literature/HalfsSaga'': Worried that her husband King Hjor could reject her twin sons because of their ugliness (which would result in their exposure), Queen Hagny swaps them with the handsome newborn son of a serving woman. Unfortunately the false prince turns out timid while the twins are aggressive and grow much faster and stronger. When the boys are three years old, the poet Bragi correctly guesses that the prince is fake and that the twins are the true heirs, causing Hagny to come clear and swap them back.
* Ava brings Isabel her newborn baby brother to replace her own dead, deformed child in ''Literature/KingdomOfLittleWounds''.
* {{Discussed|Trope}} in ''Literature/IfIStay''. Mia jokes that she thinks she was this because her family loves rock and she prefers the cello.
* In the Ancient Egyptian romance ''Literature/{{Uarda}}'' the son of a noble Egyptian is exchanged with that of a humble gardener - a fact that becomes ''painfully'' obvious to the reader long before the reveal.
* ''Literature/MidnightsChildren'' has [[spoiler:Saleem]] and [[spoiler:Shiva]]. One was born from a wealthy family, while the other was born from a poor family; the midwife was in love with a Communist at the time, and so she switched them to echo his principles. One of them ([[spoiler:Saleem]]) says he doesn't care about his true parentage, and still considers his adoptive family his true one his family. Notably, this is one of the few twists in the book that Saleem doesn't spoil in advance or even hint at. Padma feels betrayed by it as a result.
* In ''Life Expectancy'', by Creator/DeanKoontz, two women give birth on the same night, with the same medical staff caring for them. One [[DeathByChildbirth dies after bearing twins]], the other survives the stillbirth of her child. A kindly nurse, faced with a psychotically enraged new widower - when we say "psychotically enraged", we mean ''"shot and killed the attending doctor"'' - manages to not let him find out he's the father of twins, and he removes the baby he knows about from the hospital. The other baby is switched for the stillborn child, whose mother is not yet aware her own child did not live. [[spoiler:The switched twin becomes protagonist Jimmy Tock, while his twin is villain Punchinello Beezo.]]
* A subplot of Fannie Flagg's ''Standing In The Rainbow'' involves Minnie Oatman (of the Oatman Family Gospel Singers)'s baby being inadvertently switched at the hospital with that of a local socialite. While the Oatmans are plump and gregarious, Betty Ray is slender and painfully shy.

* An episode of ''Series/{{Dinosaurs}}'' revolved around the possibility that Baby Sinclair had been Switched At [[strike:Birth]]Laying. It's heavily implied that this is in fact the case (the other baby is even green, like the rest of the family) but [[StatusQuoIsGod of course]] he ends up remaining with the Sinclair family. That being said, baby Aubrey turned out to be so cloyingly sweet and agreeable that the Sinclairs [[WeWantOurJerkBack sent him back to his family.]]

When they harass her about not having a mother, Sarah forges a letter from the doctor confessing to switching the babies by accident. Aunt Hetty catches on, but first suggests that they switch the girls back, since the mothers had earlier made a big point of her not being able to understand motherhood, having never given birth.
* ''Series/VeronicaMars'' contains an example. [[spoiler: Veronica discovers that her friend Mac was switched at birth with Madison Sinclair. When the mistake was discovered several years later, the hospital paid a substantial amount of money to both families, but the parents decided to keep the babies they were raising. Madison's parents managed to get rich, while Mac's father's business venture failed. Madison's mother is interested in getting to know her biological daughter, but Mac's parents aren't.]]
* ''Series/OneLifeToLive'' is the baby switch headquarters of American soaps. In the early 80s, Karen Wolek switched her sister's dead baby for a living one, a switch that went on for ''years''. Later, Gabrielle switched Alicia's dead baby with Brenda's living son. In 2004, a major CrossOver with ''Series/AllMyChildren'' saw Kelly from ''OLTL'' raising the child of Babe from ''AMC'', who in turn had best friend Bianca's baby.

* This trope is what [[NotBloodSiblings prevents]] straight BrotherSisterIncest in the Korean drama ''Series/AutumnInMyHeart'': the main couple were raised as biological siblings, and in their teenage years, when their feelings become muddy, it's revealed that she was inadvertently exchanged with another baby girl because her older brother, a toddler back then, entered in the nursery and exchanged the name tags.
* Done on ''Series/{{Neighbours}}'' when Bree is revealed to have been switched with another baby at birth.
* On ''Series/TheDickVanDykeShow'' episode "That's My Boy?!" Rob was convinced that Richie had been switched with another baby at the hospital, because the the hospital kept confusing Richie Petrie with Richie Peters (delivering the wrong flowers etc.) and baby Richie didn't look like either parent. That is, until he met the Peters family, [[spoiler:who were black]] resulting in one of the longest laughs in TV history.
-->'''Rob Petrie:''' Why didn't you tell me on the phone?
-->'''Mr. Peters:''' And miss the expression on your face? [[spoiler: He's played by Greg Morris, later known for his work as Barney Collier on ''Series/MissionImpossible''.]]

[[folder: Real Life ]]

* Modern, western hospitals go through ''extraordinary'' measures to prevent this from happening, after some well-publicized (and very expensive) cases that came to light with the advent of DNA testing.
** In Russia, it recently happened to two infant girls. The families still see each other frequently, and the girls still say "Mama"! when they see the other family's mother. Who miss them, actually.
** One woman discovered that this happened to her father when she got her DNA tested for fun. Expecting Irish and British Islands markers, there was instead Eastern European markers in her genes, and she went on a genealogical and historical hunt to discover whether her mother had had an affair, or if she herself had been switched at birth.
* In ''Series/BeyondBeliefFactOrFiction'', this story was introduced as true: A woman discovered, thanks to her premarital exam, that her blood group wasn't like her parents'. She came to the hospital with her fiancé who was born the same day and at the same place on a confusing night (New Year's Eve, during a tempest). The mess led the nurses to write the wrong sex on minute books. So she was switched at birth, [[ItsASmallWorldAfterAll with her own future husband, no less.]]
* As mentioned under Film, this happened to Kimberly Mays and Arlena Twigg which inspired the aforementioned TV film ''Switched at Birth''.
* Brood parasitism is a strategy used by certain bird species, most famously the Common Cuckoo, as well as some species of bee and wasps. Cuckoos combine this with KillAndReplace. Some cuckoos push away the birds' eggs and lay their own. With others, the chick itself (which hatches earlier than the host eggs) will push the eggs out of the nest to their doom. To add insult to injury, the Cuckoo chick is usually much larger than even its "parents" which means they have to struggle to feed it.
* Inverted in the case of Patricia Noonan and Shawn Lake, two similar-looking teen girls who were involved in a car crash. Lake died and Noonan was in a coma; Noonan's parents were informed that their daughter had died and Lake's that theirs was in a coma.

Whitney Cerak was believed dead, and was alive; Laura VanRyn's family had thought that the girl they had cared for was actually Whitney. A book, ''Mistaken Identity'', was written about the event.
* [[ In Columbia, two pairs of identical twins were switched and raised as fraternal twins.]]
