I'm sorry but you won't receive any answers, lots of channels with content for children are dead or almost, between June 25th and July 11th and the answer @teamyoutube is always this. For many of us this is our job and now we don't know what to do 
@TeamYouTube Hello! Thousands of kids channels saw a massive drop in views on the 11th July. The algorithm has stopped suggesting our channels. Is this a bug? Please look into it.
