Does the size of a pregnant woman's bump vary between pregnancies? Our midwife looks at the measurements.

Raisingkids member's problem
I may be a tad neurotic, but after a miscarriage and a late termination in the last two years, I am more concerned then ever that this pregnancy is OK. I am 25 weeks and have just been for a midwife check up. All is ok, she measured my stomach and I am 21 cm. But at the same stage with my first child I was 24cm and she was a big baby (nearly 11 lbs at birth). Should I be concerned that I am smaller this time? The placenta is positioned differently - with my first child it was at the front, now it is at the back. Can that influence the size of my bump? The midwife said that the most important thing is that I follow my own curve, but is it normal that bumps differ with babies, and can I still grow so that I have a big baby again (kind of runs in the family to have big babies) or might this one be a lot smaller, or rather more average?

Midwife Genevieve Kingston's Advice
Eaach pregnancy is different, simply becuase each baby is different.
Some curl up more, some stretch more. When the midwife says you need to follow your own curve, she means that if at each visit you measure 2 -3 cms smaller, that is not grounds for alarm. But if you were suddenly to drop, ie measuring right for dates up until 34 weeks and then you only grew 1 cm, that would mean something had caused the baby to stop growing.

The position of the placenta would make little difference to how much you measured, and as to what weight this baby will be, it's impossible to tell.
