When the party is over and parents start arriving to pick up their kids, stand at the door with the birthday child. As the kids file out, have him give them each a loot bag and their finger paint art. Make sure he thanks them for coming and for the gift he received.
The Barney birthday party will be a great success and it is a reasonably priced party to host. Have fun and as soon as the party is over, start thinking about what next year’s party theme will be.
