Ok...

I am 10 and knowing what I know... I am slightly unhappy. I got the app for my little brother and sister and they are finding violent and odd videos. Its addictive, but you dont display all videos from channels, even when they are ok. There should be a feature where kids can "subscribe" to a channel and get notified from YT kids when a new allowed video comes out. There should also be a more clear way to turn off search+ voice search in the middle of using the app. I understand you dont and cannot go over every video making sure it is appropriate, but you should at least go over the ones that people report. I reported a video nearly 2 years ago and it is still on my tablet, my younger brother and sisters tablet and my best friends tablet, just frolicking around. I understand the block feature, but you really need to go over these videos.

Over all, the app needs to work on its content filters, reporting videos, and more features to keep kids having fun with it. It is addictive, but as of now, Id say that the app is better for 8 years old and up rather than toddlers.
