My parents have always had my nephew for sleep overs, days out as he for older and stuff since he was a baby, he’s 9 now, whenever they have him they make an effort to take him out somewhere, they don’t have loads of money but they go to free places, local gardens, woods, play areas etc and he loves it! He’s been going to one of the big gardens round out way since he was a toddler with my mum and dad and it’s his fav places as he loves playing in the trees and bushes etc and pretending there are dinosaurs there! Even when they don’t go out my mum would be playing with him, reading, drawing, everything! They do nothing, at least you don’t see them doing anything and Altho not my cup of tea as I’m not a parent, surely they could get loads of content out of that that a lot of people would really enjoy!!
