My EDD is on 21 April 2009, am near to 36 weeks now, and I went for my checkup last week, and my baby girl is 3.1kg already!!! I asked my gyane whether my baby girl was too big, but he didn't mentioned anything and said it's ok. But to me, i thought it's big. I'm in the same situation as you, I dont't snack in between meals, I cut down all sweet things few months ago and I also dont't go for late night supper. I'm also wondering why my baby girl is big.
By the way, how much weight have you gain?
