Six. It's more coracle than ship shaped, but it has a cheery soul.
And polka-dotted five. Polka dots make me smile. We had a Polka Polka-dot Parade Party for Blue when he was two. We had round foods (grapes, cookies, satsumas, olives, etc...). Folks came dressed in dots. The walls were dotted with big construction paper circles. There were dot-to-dots and dotting with bingo markers to do, and pin-the-dot-on-the-dalmation. One friend brought his accordion and played polkas while the kids paraded around the house with their own instruments. Everyone had a good time, except Blue, who became overwhelmed and went outside to take a break, sitting in the sandbox crying. Lesson learned, we didn't throw a party for anyone under the age six after that.
