Alex whined, "He's (Wayne) never here for my birthday!" So we had an un-birthday party the day Wayne got here. I went to the dollar store and got balloons and balloon theme party supplies; table cloth, plates, cups, napkins. I blew the balloons up after the kids were upstairs and hung them from the ceiling. I also got a pinata that I filled with little toys.
The kids big and small had fun whacking the dragon pinata.
Each child got a present, which was already bought for their real b-day.
