We did 30 days with no kind of TV a while back. I'd like to do it again permanently, but it's such a cheap source of entertainment. I know the kids would find something to do. It's me I'm worried about haha. I think thats great you are doing the no video games. They can be toxic for some kids. My boy is like me and has no self control when it comes to screen time. I have to give him a heads up before it's time to turn it off. It helps that we explain things to them instead of just saying "because I said so" like my parents did.
My wife is a teach. I don't have any say on the books. Which I'm okay with cause we read to them every day. They love it and are always asking to read more.
