my ds will be four in a couple of months. i am planning on doing a joint birthday party with a friend to share stress/cost etc as have never thrown a kids party before (previous birthdays with family). ds at nursery with a class of 20 and invites to parties so far have gone to all classmates. my friend and I were thinking three friends each plus parents/carers and that seems like enough! there are a couple of children ds would really like to invite from nursery but I'm thinking it might be better to have none and just a couple from outside of nursery so no-one feels left out - what do you think?
