I think we've started a new birthday tradition. After making Skyler a pie for his birthday, I couldn't go without making one for Eleanor as she turned three last weekend. We're waiting until the end of the month to have a party (when my in-laws will be able to celebrate with us), but we had to do something to recognize her big day.
So we kept it simple with a little family pizza dinner and some yummy pie afterwards. She insisted on having only one candle to blow out. I guess it's easier to blow out that way, and why shouldn't we make wish-making a little easier for our little ones?
