I wouldn't worry about it too much. My little brother (2 yrs younger) and I share a birthday and it's 5 days after Christmas. We joked about being slighted, but really we never knew any different. Now I'm preggo with my first, due 4 days before my b-day, the day after Christmas. This kid might have to share with me and his uncle or Christmas or New Years or one of the holiday Eves. Again, he won't know any different. Make a big deal out of baby's big day, no matter when it is and I'm sure any shared Bday won't matter too much!
