This question may have been asked before but how did you celebrate your birthday when you were a child?
My mom always made us a cake that we got to pick out the flavor/icing. I had a couple of parties, mostly neighborhood kids (only girls). When I got up into junior high I had a couple of slumber parties.
Joe on the other hand, never celebrated his birthday when he was a child. His parents just didn't do it. They didn't have the money with seven kids and so they chose not to do it. Needless to say, birthdays are not a big deal to him and I have had to adjust.
My kids got parties, whether just family or friends or both.
