It's all parenting problems. I have 2 small children and when I am out I notice other families with similar ages kids and the whole damn family is on thier phones at the dinner table cant hardly look away long enough to order a meal. Hell there are kids in the daycare we use that are jammed behind a tablet in a chair when I drop my kids off and the same chair same kid same tablet in the same spot when they get picked up. Nothing the owner of the daycare can about it. (Parents are pricks according to her)
I think its lazy parents getting away with entertaining thier kids with as little effort as possible on thier part. I wont blame the kids or the product. But either way it isnt good for them.
We call it the electronic babysitter and can make for some easy parenting.
We try to limit our kids to an hour of TV and 30 minutes of IPad or phone time a day. My kids are at a really tough age (5, 3 and 8 months) and throwing an electronic device in front of them would make our life so much easier, but we don't.
Also, what they watch is important too. If she had her choice my 5 year would watch stupid youtube videos of adults (hands only) opening up random kids toys and playing with them using kids voices. instead, I have a curated playlist I created for her so that I can make sure the videos she is watching is educational.
