What are some animes like Card Captor Sakura that are CLEAN that I can find in english?

Pokemon
Digimon

To be honest your not gonna find that many "clean" anime's, if tu don't want him/her watching anime's like that then he/she shouldn't be watching anime. por that age I was watching animes with people getting their limbs ripped off and being división, split in half.

A Little Snow Fairy Sugar is a really adorable anime I'd recommend for kids~

tu could watch Mew Mew Power, that's in english.

Sailor Moon and Kaleido star!!! :D

Fruits Basket <3
even if u already watched it then u gotta watch it again :)

Squid Girl and Lucky Star, Lucky estrella is all in English on on Youtube, tu can watch the first season of Squid Girl in English on Netflix if tu have it.
