I read the book Screentime Solution by Emily Cherkin (also Anxious Generation and Screen Schooled). Basically her advice is to be screen-intentional as a family. Right now my husband and I make an effort to put our phones away when we come home from work and spend time with each other and our toddler. Another thing is that she does not have any of her own internet devices. It’s the family tv and my iPad that she uses (with supervision and sparingly). We have a few devices she uses that are dumb (old gameboy and old iPod) but still rarely. Restaurants and family dinner are screen free zones. Even as she gets older we’re more likely to get a dumb phone and a family phone than let her have her own device. Something from the book was to let your kids have access to the internet and social media when you’re ready for them to see porn (not necessarily her opinion but an anecdote) and there’s no fool-proof parental controls. We are getting a family computer soon to teach her typing, using a mouse, and general computer skills but that will not be unsupervised or even internet connected most of the time. My goal is to teach her responsible use and to always have a line of communication open about it.
