Sounds like you have all that you need for a successful party for 1 year olds. They really don't pay attention to entertainment, nor are they going to play with each other. For a first birthday you have what you need. Save your money on an entertainer for the kids until they are older (4/5 years old). Now if you really want to entertain, then higher a band for the adults. The little tykes will dance to the music and the parents will enjoy it as well. Makes for cute videos of the babies trying to dance. Good Luck and have fun. The first birthday is soooo exciting!! Congratulations on the first year.
