Obligatory Large Family Twins

In a family with many children, there will inevitably be one set of twins

Name Space:
Main
Page Type:
trope
In fiction, a family that has many children will most likely have at least one set of twins (or possibly even triplets).

This trope can be used to increase the size of the family while not having huge age gaps between siblings. It also helps make make siblings in a large family more distinguishable. By having two be twins, the writer makes it easier for themself by grouping two into a set who can either share a personality or stand out via contrast.

Examples:

Anime & Manga
  • Brock from Pokmon is the oldest of ten siblings. The youngest two, a boy and a girl, are twins.
  • Moko, best friend to Skip Beat! protagonist Kyoko, is part of huge, multi-generational family. note  Of her 7 younger siblings, there is one confirmed set of twins. Her three older siblings (aged 24, 22, and 19) all have children as well and live at home with Moko's parents. Though not confirmed by the author, the style in which some of Moko's nephews are drawn makes it possible that her older sister has a set of twins and that her eldest brother's two children are twins.

    Real Life: Probability and biology makes this sorta likely after a certain point?

    From Wikipedia:
    The most common kind of multiple birth among humans, occur in about 1 out of every 80 pregnancies.

    And, a large family may be due to a frequency of twins+...

    This is a subtrope of Massively Numbered Siblings right? 'Cause that means at least 5 children, And so Pinkie Pie doesn't count...

    ^ She has a large family for the series though. Most ponies only have one sibling, if at that.

    It's been a while since I took a probability/ statistics course, but I'm not so sure that "with each pregnancy the chances of having multiple births increases." Correct me if I'm wrong, but I think the chances of having a multiple birth remain the same for each successive pregnancy unless there's some intervening factor (like the use of fertility drugs? or else a predisposition towards twins, or a large span of time between pregnancies). Maybe that sentence should be changed in the description?

    ^ How about age in general? ... Perhaps he means "With every birth, the chance that a family will have an occurrence of multiple births increases, as each birth has a chance to be a multiple birth, and those chances stack up."

    Or something.

    On the Classic Disney Short "Casey Strikes Again", a sequel to Casey At The Bat, Casey has nine daughters, enough for a woman's baseball team. They include not just twins but a set of triplets as well.

    I'd avoid using "always" in trope names; better to let the examples show how common the trope is.

    The Loud House: Lana and Lola are twins out of the 11 child family.

    Storks: Tulip discovers her birth family at the end of the film and there's at least one set of twins in the family as they all rush to give her a group hug.

    Wait... What is the Narrative Meaning or whatever, that makes this a trope, instead of just a pattern?

    I'm confused as to why you didn't add my Dream Daddy entry, when it uses the exact same logic as your My Little Pony entry.

    Wish the title changed a bit. Linking to tropes that have too much words is always a chore.

    Something like Obligatory Large Family Twins

    It needs a narrative purpose (To...make the family bigger? To make the twins/triplets/whatever-ets "stand out" in a large family because of the circumstance of their multiple pregnancy? To easily lend characterization to the twins when introducing the family because of all the Twin Tropes we have?), otherwise it's just Massive Numbered Siblings with twins and thus, not really worth troping. At best it's a Trope In Aggregate.

    Also, including families of three kids might be pushing it — standards of the work or no, by the standards of the very human creators, it's not really that large of a family. See the description on Outnumbered Sibling: "a family of three doesn't make this trope particularly interesting."

    Re: "chances of having a multiple birth stack up": Genetics doesn't work that way; each pregnancy is independent from the others. However, there is a link between the age of the woman and her chances of having multiple births — specifically, older women are more likely to have multiple births, probably because of hormonal changes brought on by age.

    ... Yeah... I'm really unclear. I mean, like, if you have a woman with 9 births, she's more likely than some woman with 3 births, to have multiples, 'cause there's more chances for any of their births to be a multiple.

    As far as narrative significance goes, usually when a family has Massive Numbered Siblings it's hard to make all of them distinct and important. By having two be twins, the writer makes it easier for themself by grouping two into a set who can either share a personality or stand out via contrast.

    As the OP mentions, it's also a way to have a family with lots of siblings who are all plausibly close in age.

    I don't think this is a trope.

    I'm liking this trope, since not only will a large family more likely include a set of multiples, but it's also a 'cheap' way to have many children in a family, not just to create the contrast, but potentially to in itself create drama, since they will naturally attract attention, while also taking it from The Hero, who gets ignored because Babies Need Care/Mom is Exhausted.

    If each pregnancy has a 1 in 80 chance of being twins, then there's a 6% chance of at least one set of twins in 5 pregnancies, and a 12% chance in 10 pregnancies. Or to put it another way, if Mom gets pregnant 10 times, there's an 88% chance that none of the resulting children will be twins.

    That's a long way from expecting large families to include a set of twins just based on the odds.

    In The Broons, the family of eleven includes Maw, Paw, Granpaw, Hen, Joe, Maggie, Daphne, Horace, "The Bairn" (Scots for "The Baby") and "The Twins". One is called Eck (short for Alexander) but the other is unnamed and they are referred to In Universe as "The Twins" too.

    Pretty sure the Silmarillon does not have a character called Fëanor.

    It's kind of a gray area whether this is a trope or not, but I can think of another example:

    The Seeker: The seventh son of a seventh son has magical capabilities in this world, and there is a twin in his family. It's his twin brother, no less, though said twin brother was mistakenly kidnapped at birth.
