TubiTV has plenty of Kids shows, cartoons and family shows:
And Family movies:
TuiTV is free to watch but they show different content to US/Canada/Australia users depending on IP, if you have a VPN and you change your IP you will see really different content. It is blocked in some European countries.
If you like anime, I really enjoyed Locodol, a Japanese manga series about "Local idols", they call them "Locodol".
It is free to watch but in Japanese with English subtitles. Search Crunchyroll for similar series.
