Play School and Peppa Pig, so 30 minutes a day max, and I only use it when I'm desperate. Like KitFaerie, my DD1 gets really cranky after watching it, she seems to lose the ability to initiate play, so just ends up whingey and clingy afterwards, and it's not worth it.

She watches on the iPad, we don't have a tv, so it's easy to play the out of sight card.
