Why Was Blue Ivy Allowed to Watch the VMA's?

So Imma just say what I am thinking: Blue Ivy is too young to be watching her mothers performance!

I love watching the VMA's but I know my children need to be in the bed or in another room at least. The performances are so sexual these days, and it is not something children should be watching.

I just don't understand why someone would want their child watching a burlesque type performace anyway.  Is there nothing we wont protect our children from?
