Can’t really praise enough YouTube Kids App! Amazing way to help parents and allow kids watch kids friendly videos , I really wish one day there would be an option to only watch subscribed channels not only avoid blocked ones. Thanks @TeamYouTube @SusanWojcicki
Wow ! Just tested it , this is AMAZING and exactly what I was searching for
I also discovered something that’s even better , you can choose different collections for each child so they don’t have to watch the same thing if they are of different age ! THANKS A MILLION 
The “approved content only” setting lets you hand pick videos, channels, and collections for your child. More info here:
