Baby Yoshis are newborn Yoshis born out of Yoshi eggs first appearing in Super Mario World. The only Baby Yoshis are found in Star World. Feeding enemies to the Baby Yoshis will make them turn into adult Yoshis. It takes roughly six enemies for this to happen. However, if a baby Yoshi eats a Star, it'll grow up instantly.

The Yoshis in Yoshi's Story were newborn, however they didn't look small at all, and looked like they were grown up Yoshis. During the story sequences at the beginning and ending of the game, they were shown to have smaller and less developed bodies in contrast to the Yoshis seen only on the very first page in the intro.

A baby Yoshi called Little Yoshi appears in Tetris Attack. He might be a Baby Yoshi even though he is not as little as a Baby Yoshi. In Super Mario RPG: Legend of the Seven Stars, a pudgy Baby Yoshi appears as an inhabitant of Yo'ster Isle; Mario can feed Yoshi Cookies to this Baby Yoshi.

A group of Yoshi children calling themselves the Fearsome Five were encountered on Lavalava Island in Paper Mario. When first encountered, they were being watched over by Sushie, though they were thinking up plans of their own. When Mario later returned to the village after he discovered that the path to Mt. Lavalava was inaccessible, the older Yoshis were going berserk over the Yoshi children's sudden disappearance. Mario helped Sushie down from the tree that they trapped her in, and found all five Yoshis.

Yoshi from Paper Mario: The Thousand-Year Door is small like a Baby Yoshi, however he has hair and he talks. A Baby Yoshi was born in the end of Yoshi's Island DS. He is one of the Star Children. This Yoshi might be the Yoshi or just a regular green Yoshi.

Yoshi appeared as a Baby Yoshi in the Super Mario World episode "Mama Luigi"; unlike the Baby Yoshis of the Super Mario World game, Yoshi was shown to be able to move on his own as a baby and didn't possess any shoes on his feet.
