I don't feel like I have enough toys for my 17mo DS. He is at nursery full time but when we are at home he has a lot of small toys like cups, soft toys, squishy animals, masses of books, a couple of puzzles, random assorted stuff like stacking cars, pull along do-dahs and so on. But for big stuff he doesn't have much - there's a train set, some lego, building blocks, musical intruments, a post box and that's about it.
What else does he need? I look on Amazon and in ELC but never see anything that seems appropriate. Mostly he just likes to move things around or play with my stuff but I feel like I should just have more - what would anyone recommend?
