Needs Option to Block

My three year old daughter and I really like this app. However, she has come across one ladies videos who plays with dolls and pretends they are her children, creepy but what ever, the problem I have is that she has her "babies" say she is a bad mommy when they dont get their way. Well now my daughter is doing the same to me. I have yet to find a way to block her channel, if there is one. Please make a way to block channels.
