"My Little Pony" causes behavior problems

Theres no doubt. Since Lucia started watching the incredibly trashy cartoon series called "My Little Pony" she has become sassy, cranky and rude. I'm astonished how a cartoon can mess up a little girl in such a short amount of time.
I called Netflix tonight to hear how I can set up my streaming service to remove certain titles, but there was no way to do this. Lucia will therefor no longer watch anything on the iPad :( Bummer because she really likes it over the TV, but if there a show on TV we have better control over what she is watching.
