My kid is 3 but this has been a big issue on my mind lately. I’ve read The Anxious Generation, The Screentime Solution, and The Art of Screentime over the past 9 months (with some other tech-adjacent books). My husband has also recently had a turn-around on tech for kids. I think our big thing is no personal devices for the little one for a long time. Family computer in a common area. Family cellphone that can be used when she’s not with us. Family tv in the living room. Family iPad that is used for specific tasks.
