* Duncan, Kimberly, and Jing in ''WesternAnimation/{{Duncanville}}''

* Duncan, Kimberly, and Jing in ''WesternAnimation/Duncanville''.

* The two elder siblings are often very close in age, between 1 and 3 years, or twins. Sometimes, this rule is bent, the age gap might be bigger or medium sized (could be between 4 and 9 years), but never from PracticallyDifferentGenerations. The eldest sibling can be either sex, but it is usually a girl. The odds of the oldest being a girl seem to go up with the size of the age gap between the two older siblings.
* On the opposite end of the scale, the youngest often is farther from them, between 4 and 19 years younger. Rarely, the baby will be 2-3 years apart from the middle child.
* The boy and girl have an average of ages between 7 and 15 years: not too young children and not too old teens, either. Sometimes their ages can differ, and the ages can range, but they are no younger than 4, and no older than 19.
* The baby is not an infant or newborn: more like a toddler between 6 months and 2 years old, but typically too young to talk in full sentences (or talk at all). Sometimes, this isn’t the case if the baby is smart (see down below).

** Downplayed with Cleveland Jr., Roberta and Rallo in ''WesternAnimation/TheClevelandShow'', as Rallo is 5, Cleveland Jr. is 14, and Roberta is 15, but they could’ve been like this in flashbacks.

* Pacha and Chicha's children in ''Disney/TheEmperorsNewGroove'', even though the baby was only seen for a few brief seconds at the end of the film.

** Cleveland Jr., Roberta and Rallo in ''WesternAnimation/TheClevelandShow''.
* Arthur, DW and Baby Kate in ''WesternAnimation/{{Arthur}}'', although DW is only four years old, eventually aged up to five.

* On the opposite end of the scale, the youngest often is farther from them, between 5 and 14 years younger. But if you break the rules with the boy and girl ages and make them younger, they could be closer, or if you extend their ages, they could be farther apart.
* The boy and girl are often between ages 7 and 15 years: not too young children and not too old teens, either. Sometimes this rule is bent, and the ages can range, but they are no younger than 4, and no older than 19.
* The baby is not an infant: more like a toddler between 6 months and 3 years old, but typically too young to talk in full sentences, sometimes this isn’t the case (see down below).
* Just because one can't walk or talk yet does not mean that the infant sibling is [[TheLoad good for nothing]] or powerless. On the contrary, the infant is often shown to be the most powerful in the family (if applicable), or a BrainyBaby, or a LittleMissBadass. Even when they are only the PluckyComicRelief for most of the story, the baby can save the day at the very end as the [[BigDamnHeroes Big Damn Hero]].

* The baby is not an infant: more like a toddler between 6 months and 3 years old, but too young to talk.

* The two elder siblings are often very close in age, between one and three years, or twins. Sometimes, this rule is bent, the age gap might be bigger or medium sized (could be between four and nine years), but never from PracticallyDifferentGenerations. The eldest sibling can be either sex, but it is usually a girl. The odds of the oldest being a girl seem to go up with the size of the age gap between the two older siblings.

* ''Series/MadMen has the Draper children; Sally, Bobby, and baby Gene, although their parents split up soon after Gene's birth, so the "family" aspect is downplayed.

* At the end of ''Return to Litreature/PlanetTad'', the title character Tad and his ChildProdigy / AnnoyingYoungerSibling sister Sophie learn that their family will soon become this, with a new baby boy on the way. Neither is very enthused at first, but Tad begins to warm to the idea after learning that he will be a role model for his little brother, someone who can teach him right from wrong (he and his father agree that they can't count on Sophie for that) and that he'll be getting his own room.

* Subverted in ''WesternAnimation/TheBuzzOnMaggie'' with two boys, a girl, and a baby.

* Subverted with the Freemaker trio in ''WesternAnimation/LEGOStarWarsTheFreemakerAdventures'', with Zander (boy), Kordi (girl) and Rowan, who is the youngest, but as a preteen, not a baby.
