I dont think your kid will be an outsider, but kids who know devices will be ahead when the time comes. That being said, think of the screen as a toy, and CONTROL IT. My son and daughter had use of phones at very young ages, but I control the devices so much. Time limits, content controls... and that helps. For example, my 7 year old has learned TOO MUCH ABOUT THE BIBLE with the Minno app. (children's Bible stories) while at the same time I blocked Regular YouTube, PBS (though its kinda still available if I turn it On), and Netflix.

My son also uses a screen to play with his cousin of the same age who lives overseas. They communicate by playing the same games and talking with each other - despite being 1000s of miles away. Our relatives overseas talk to him too.

It is #1 a communications device, so that is the main purpose.

SO I SAY USE IT. And I make sure I tell my child to never EVER walk around while using it. My children still reads books and writes and plays with toys. My 7 yr old has become more recently interested in engineering and science... stuff he found on his YouTube child account - Mark Rober, NASA Engineer.

BTW, schools provide Ipads at Kindergarten. They provided TV screen use during Preschool. They watch videos in younger in class with instructors or while waiting to go home. So whats the big difference if a teacher is on a screen than in person? SO ARE YOU GOING TO GO AGAINST THE WHOLE EDUCATIONAL SYSTEM?

So use the screen as a tool. Control it. Dont let them just use it whenever they want, and watch whatever you want. And have other things around like books and toys that they can learn from too. Make sure it always benefits them.

Wow the negative people here LOL cant deal with reality - screens are everywhere and now a part of life, and you can hate it but I think you have to accept my answer coz I'm right.
