I need to buy a couple of gifts for two boys age 3 and 4. The issue is they seem to have a lot of toys and I know they like Spider-Man but already have a lot of Spider man toys /dress up etc. Also their parents are quite well off and dress them often in expensive clothes so I don't just want to buy clothes in case they don't get worn.
Any ideas of a nice gift that wouldn't just be adding to a mountain of toys/hidden in a wardrobe somewhere?
