I know there's the theory out there that all subsequent children will be larger / heavier than the first child, but I'm wondering if that holds true in reality. With LO1 being 8lbs 10oz with a difficult vaginal delivery (a CS was basically not an option), I'm a bit intimidated about the size of future children and how it will impact birth.

Part of a factor, I imagine, was my pregnancy weight gain. I was hungry all the time and gained 40 lbs. I wonder if I try to be more disciplined next time, if I'll gain a more healthy amount (25-35) and have a same size or a bit smaller baby?? Obviously nothing at all to endanger their health, though.

What was your experience, and influencing factors?
