I would love it! Really, it isn't very often that kids celebrate their birthday on the exact day, you don't see too many birthday parties on Tuesday afternoons, kwim?
He could choose between wanting to celebrate it on the 28th or the 1st, whichever is more convenient that year. Also, birthdays are to celebrate how many years old you are, not how many times that exact date has passed. I think it would be a really fun birthday to have - every 4 years, it would be extra cool!
Kids get teased for a billion reasons, and if it isn't about their name, it will be about their birthday, or their clothes, or that they live in a yellow house, or have or don't have freckles. THis kid isn't going to have parents who look or behave like everyone else's, so our kids are going to have to get used to rising above teaing and not base their self esteem on schoolyard feedback - for whatever reason.
THe midwife said she wouldn't be surprised if I go today (second pregnancy, head is already engaged and fixed), so tomorrow is a possibility!
