First and second birthdays, under $100 (very small parties at the house with family and a few friends, made the cake and other food myself).
Third birthday party, way too much - around $450 for a gym-type place with instructors, bought extra decorations, goody bags, bought the cake (couldn't figure out how to make one big enough myself), pizza, etc. I did it because other kids at DC's school were having similar parties and it seemed like a good idea. But I think next year we will go back to something at the house with a few organized games. Growing up, my birthday parties were always low-key affairs with a homemade cake and the neighborhood kids except for my one party at Chuck E Cheese. I have only fond memories of those early birthday parties
