* In ''Literature/{{Twilight}},'' [[{{Dhampyr}} Renesemee]] is [[InformedAttribute supposedly]] as intelligent as an adult, though it's a bit ambiguous because a.) she also has RapidAging and b.) she still tends to act more like a baby than an adult. Nevertheless she's able to read within a few weeks of birth, at which time she looks about three.

* ''Series/Charmed1998'': Mere days after he's born Piper and Leo's son Wyatt works out that if he cries the magical alarm Aunt Paige set up will go off and bring his family running. He quickly starts setting it off deliberately to get people to pay attention to him.

* Baby Brain in the ''ComicBook/SevenSoldiers: The Manhattan Guardian'' flashbacks to the Newsboy Army.

* ''ComicBook/FantasticFour'': Valeria "Val" Richards, the second child of Reed and Susan Richards, was revealed to be a genius... as an '''''infant'''''. She takes after her good old TeenGenius dad, a borderline ChildProdigy himself, who privately speculated that she would start playing chess by the time she reaches '''''age 2'''''.

** Lisa was no slouch herself, being able to change and pin her own diapers as a baby. While Bart, then as now, was less of a standout, his preternatural talent for mischief was such that he managed to light his dad's tie on fire ''the very first time'' Homer held him, when he was ten minutes old.

* Legends of Myth/{{Merlin}} often have him suddenly speaking perfectly around the time he is weaned. This is convenient, because this is also around the time when his mother is about to be put to death for getting pregnant out of wedlock; Merlin, with his prophetic knowledge, testifies that his mother was [[ChildByRape raped]] [[HornyDevils by a demon]] in her sleep and thus gets her spared.

* Mannish Boy of ''Manga/JoJosBizarreAdventure'' is one of [[BigBad Dio]]'s superpowered assassins, despite being a baby. In general, whatever process causes someone to develop a [[FightingSpirit Stand]] also causes them to gain the intelligence of an adult human, even animals and ''plankton''.

* The premise of the movie ''Film/BabyGeniuses'' is that all babies are like this until just before they learn to speak, at which point their intelligence collapses.

* While Cassandra Cain is illiterate even as an adult, she had a genius for the martial arts since she was an infant. One flashback panel shows her teething on a shuriken... and then hitting a bullseye with it on a target on a far wall.
* Valeria "Val" Richards, the second child of [[ComicBook/FantasticFour Reed and Susan Richards]], was revealed to be a genius... as an '''''infant'''''. She takes after her good old TeenGenius dad, a borderline ChildProdigy himself, who privately speculated that she would start playing chess by the time she reaches '''''age 2'''''.

* Jenny Quantum of ''ComicBook/TheAuthority'' is able to speak in full sentences by toddlerhood and even before then was able to recognize opportunities where [[GooGooGodLike her powers]] would be of great help towards the Authority.

* "[[Recap/DextersLaboratoryS2EP38 LABretto]]", the OriginsEpisode of ''WesternAnimation/DextersLaboratory'', shows Dexter talking minutes after being born and building machines while still in the crib. Professor Hawk was also described as being extremely smart as a child ("At the age of four, he made history -- by receiving a college degree!")

* "Labretto", the OriginsEpisode of ''WesternAnimation/DextersLaboratory'', shows Dexter talking minutes after being born and building machines while still in the crib. Professor Hawk was also described as being extremely smart as a child ("At the age of four, he made history -- by receiving a college degree!")

** Downplayed for [[TheBabyOfTheBunch Lily Loud]]--while she may not be as intelligent as her sister, Lisa[[note]]A ChildProdigy who's technically already finished school up through getting a [=PhD=], which is a type of doctorate degree[[/note]], she's shown to be very smart someone her age[[note]]Lily's stated to only be 15-months-old in the first four seasons of the show[[/note]]. For example:

* Brainy Smurf from ''WesternAnimation/TheSmurfs1981.'' While he's an adult in the show proper, a flashback to his infanthood in the Season 5 episode "Papa's Family Album" reveals he started reading before he could even walk or talk.

* Noi in ''WesternAnimation/RayaAndTheLastDragon'', who works with a band of [[MixAndMatchCritters monkey/catfish hybrids]] to con people.

* In Creator/{{Dreamworks}}' ''WesternAnimation/TheBossBaby'', an average kid named Tim discovers his new baby brother can talk (and has the personality of a bossy CEO), and gets roped into [[MakesJustAsMuchSenseInContext a scheme to stop puppies from becoming more popular than babies]].
* "Baby Weems", a segment in Creator/WaltDisney's ''Film/TheReluctantDragon'', is about a baby who can speak eloquently from birth. He becomes a celebrity and confers with some of the most eminent minds of the day, but all that fame separates him from his parents, who can only see him from afar.

** Downplayed for [[TheBabyOfTheBunch Lily Loud]]. During the first four seasons, Lily's established as being only 15-months-old (one year and three months) and while she may not be as intelligent as her sister, Lisa (a ChildProdigy who's technically already finished school up through getting a PhD), she's shown to be very smart for someone her age. For example:

** "Room and Hoard" establishes that when she was a baby (probably around age one, since the licensed comic "It's Just a Phase" reveals that she started doing experiments at one) she kept her used diapers and studied the bacteria in her pee and poop.
