I dont think it really matters what month your baby is born in.
I'm sure each month has its good and bad things. I was a June baby, and when my mum went to enrol me in school when I was 4.5, the school said you have to be 5 by the end of May, and so they didnt want to take me and told my mum to come back next year. But, Mum made a special application and they took me. Apparently I was a clever kid and preschool couldnt see any reason for me to stay back a whole nother year.

I think its just because December is one of those crazy months where so much happens and people always reckin it would suck to have your birthday on Christmas day.. but really, what is more important? A healthy baby or the birthday being in a certain month? I honestly woldnt care if I had a baby due on Christmas or a few days later. My sister has her birthday a few days before Christmas and she hates it. But she is a bit of an attention seeker so maybe thats why (her birthday seems to just get stuck in the middle of Xmas craziness some years).

Claire was born in March which I think is a fab month. The only annoyance so far has been trying to get her into preschool for next year when she will be turning 3. The preschool year start in January, children have to be 3 by the time they start, so because she is 3 just after it starts, she probably wont get in fo next year unless other children drop out of the centre. But thats no big deal, I cant change that.

Seriously, dont worry about it. You'll have a beautiful baby so who cares about the birthdate?
