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 你 don't want him/her watching anime's like that then he/she shouldn't be watching anime. 由 that age I was watching animes with people getting their limbs ripped off and being 分裂, 拆分 in half.

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

你 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 星, 星级 is all in English on on Youtube, 你 can watch the first season of Squid Girl in English on Netflix if 你 have it.
