I have done both extremes. 1st pg I only put on 5kg, but I started at 30kg overweight. for the second I put on 19kg, I started from within my healthy BMI. the second pregnancy I was monitoring my food intake and sticking (mostly ) to healthy foods, my midwives were also monitoring my weight - at my request, because I didn't want to gain too much. 19kg seems to have been what I needed to gain for a health pregnancy.

This time I am aiming to gain less, but I am once again starting overweight - and if I do gain as much as last time, I'll deal with it after.
