On his 3rd birthday our son dressed up as a pirate captain and initially welcomed his friends to either make their own sponge boat to take home, and/or play with cars on and decorate with stickers and crayons the 2metres x 3metres paper we had taped on the floor. We drew a river, a lake and a few roads on it beforehand, and the kids did the rest. Even the shyer ones got enough space to get started with something.
As he loves boats, we threw in a few more for the birthday table: together with my son we built a ship out of sandwiches (never mind the lean, we had fun doing it 😉 ), I made simple healthy sail boat snacks out of cucumber, red pepper and cheese and orange boats. Don’t worry, we weren’t that boring, we also served more than enough sweets andd there were other games as well as free play too. But there was one more boat worth mentioning: the pretty awesome pirate ship chocolate cake my husband made to our “big boy”.
