If you are talking about Vegeta as a kid, I have seen him fight in the movie-Bardock-the Father of Goku (if i remember correctly). If you are talking about Vegeta Jr. (the great-grandson of vegeta), he is seen fighting Goku Jr. in the last episode of Draghon Ball GT.

Vegeta turns super sayian in episode 59 of Dragonball gt
episode 129
Nobody knows who Goku jr's parents are but his grandma is pan. There is only one parent know to be Vegeta jr's mother and that is known al bulma jr. look in the last episode of dragonball gt and you'll see.
vegeta
vegeta jr. Dad is,King Vegeta of Planet Vegeta which was destroyed by Freiza,and Vegta has a little brother name Tarble
He is a descendent of Vegeta and Bulma, but it is never revealed who his father is. Most likely he is the grandson of Trunks because of the age of Pan in that episode.
214 vegeta,s pride
it will be goku jr because he went supersaiyan 2 and vegeta only went supersaiyan
Bulma Jr.
