I remember the birthday parties I used to go to as a kid. They were very simple affairs. Mostly kids playing. Sometimes there were even party games. Birthday cake was always eaten (minus the icing for me as I always found it too sweet) . And there was that big pile of presents waiting to be opened by the birthday boy or girl.
Nowadays things can be a lot more extravagant and costly.
This year we decided to keep it very simple for our daughter...just like the parties I went to as a kid. Balloons, party hats, chocolate cake, scavenger hunt and prizes. Sweet and simple.
