I'm looking for creative block set add ons, etc. for my unit block loving 10 y/o dd! She loves to build-dollhouses, stables, etc. I would say that unit blocks have been one of her favorite toys, and as an early pre-teen the building has become a nice almost meditative experience for her. So, while she desires some more grown up toys/games, she also wants to add to her block play. Anyone else have an older kid who loves blocks and can suggest something to extend the building?
