For Ada's 9th birthday, we didn't do anything huge. Ada had a great idea though. She wanted to do a road rally. We had friends and cousins bring bikes, skates, scooters, skate boards, etc.... and we raced. It was so fun! Simple, nothing harder than making a cake. We even said on the invitation that presents weren't required. She still got a couple, but not an overwhelming amount like she usually gets... It was just right.
Ada kept saying, "This is the best day ever."
