My friends with young kids 3-11 all let their kids use iPads. All of the kids seem well adjusted, able to read (a worry I saw), etc. I have no idea what limits they have but the kids are social, they don't hide on their iPad when people visit but instead interact with the parent's friends.

The point being, unlike lots of comments here, I haven't seen any evidence of ill effects of young kids have access to electronics. I have no idea what these parents do and what limits they place, only that they didn't need to ban electronics from their kids lives to raise good kids.

Of course it's anecdata. One family, 2 daughters, 5 and 8. Another, son 11. Another son 11, daughter 7. Another, daughter 3.

I have also seen the opposite. Kids who can't function if their screen is taken away and are anti-social. But given the other kids, it doesn't seem to be the screen that's the problem.
