When children are young (pre-teen) they crave something more that screen time - their parent's attention! My father shared his time with me and I shared my time with my children. My father has been gone about 5 years now and when I think about him my memories go right back to the time he spent with me doing hobby things such as models, trains, etc...
Obviously kids need to be interested in hobbies but doing them WITH your kids makes all the difference!
