You were definately right, he is too young. Trust me- the kids being together are all the entertainment that's needed. It seems you have plenty of expenses with having a 1 year old's party catered and gift bags for all. If you are at the park, they will run and play and never even notice that they didn't also have a show. Just bring a few balls and a pinata and you're good to go! My daughter just had her 4th birthday party yesterday, all 4 with no "entertainment" and mixed age groups from infant to 14yrs, and just playing together was more than enough for the kids. Nobody asked "When does the show start" and they all went home happy.
