We don't have kids, but if we did this is what we'd be doing with them; Craft stuff, outdoorsy activities, board games and things that inspire their imagination, get them using their hands and bodies and developing an interest in a wide variety of things, just like my parents did for me. Some parents thrust an iPad into their kids hands, plonk them in front of the TV or video game...That's not what I'd be doing though, and both of my brothers who have children 4 and under, don't do it...I think it's smart. It seems like you guys feel the same way. Nice post and great effort with the tile crafting.
