I'm 23 weeks pg with my second, and since my booking appt at 8 weeks I have put on 6lb. I was a bit overweight at booking (BMI 29) so I'm pleased I haven't put on loads of weight up to now. But is there a 'normal' amount to put on?? With my first I'm sure i put on about a stone in the first trimester. And she was a big 9lber at birth. Curious to see if this one will be smaller because I haven't put as much weight on at the start?
