I was just wondering if anyone had any information on this topic. 10 weeks ago I gave birth to my beautiful son at a whopping 11 lb and he was my first baby. I am quite big -5'10" and certainly not of slender frame, but the fact that he was so big led to a lot of complications- I ended up with an emergency section and also had a tear to the caesarean incision as they struggled to heave him out. I won't be planning on getting pregnant again in the near future (and have been advised to wait 12-18 months anyway) but I want to be well informed before I do. I definitely ate a lot during the pregnancy, but never had any sugar in my wee (so I don't think I could possibly have had undetected gestational diabetes) and he has also stuck to exactly the same centile line throughout (95th approx). Do you think if I was very very careful about what I ate during a subsequent pregnancy I could control the size of the baby?
