I wish I could help you out with the whys and wherefores - I cook particularly small full term babies. DD1: 2.56 kg at 38+6; DD2: 2.8 kg at 40+2. Both were also only 48cm long.

Easily the tiniest babies produced in my family, despite me being one of the tallest women (around 5' 5") and having children with the tallest partner (6' 2"). I'm quite petite in build though and DP isn't broad.

I eat healthy food, but a lot of it, particularly in the first tri. I don't get m/s so I tend to start putting on weight quite quickly.

Wondering what this one will weigh and if a boy might be bigger.

Are you seeing a physio who can help with your core muscles? I still have a split from DD2 (despite her small size). :/
