Being out of town until two days before Ava's birthday didn't leave a lot of time for planning parties, etc, but when I came up with the idea of a surprise party for our little princess, Kyle was more than on board.
We invited only 5 friends, 3 of which actually came in time for the surprise. It was pretty anticlimactic to have only 3 friends and your mom and little sister running out a bedroom shouting surprise when she opened the door, but you could tell she was pleased.
The pin the tail on the pony game I made and the musical chairs tided the kids over until it was time for birthday cake and things got even better from there.
