^ What she said

I have an iphone, and my 2-y-o loves playing with it. I don't feel bad that I let him, but I do limit how long he can use it. I try to keep it for those times when you're out somewhere and need something to entertain them quietly, it's a lifesaver for that!
It is screen time, and I think we need to remember that, but I prefer it to TV screen time, as it's so interactive.
