"Diabetics tend to get big babies" - a very common line among medical professionals. And sure, our babies may be building up more body weight if our glucose levels are too high. After all, insulin is a hormone with anabolic effects and as soon as our little ones start producing their own, they'll just produce more if the blood running from our system into theirs is too sweet.
Still, I think that there are other factors contributing to a baby's weight, regardless whether the mom is a PWD or not. Not least the genetic pool.
I'm now 33 weeks along and have switched from biweekly to weekly check-ups at the hospital. Last week was a full day (well technically only half a day) of midwife (CTG), ultrasound, doctors (OB and endo are fortunately sitting at the same table at every appointment), pump nurse, eye photos and blood tests. Since the beginning of May, the ultrasound appointments have been dedicated to measuring the baby's weight and growth. All three of those appointments so far have shown steady growth, with tummy and femur measures right in the middle of their standard curve, but with a slightly smaller head, resulting in an overall lower weight estimate for our baby (10-20% below the center of the curve, but still within the "normal" range). Last week, the midwife had estimated the baby's weight to be around 1,600 g and the subsequent ultrasound came back at 1,571 g. This had the OB a bit concerned - even though the little one is still following her own growth curve - so she ordered another ultrasound before the next scheduled one, "just to make sure".
At today's CTG-appointment, the midwife estimated the baby's weight to 1,800 g. Next week will then be another ultrasound to measure it, but while I'm not too worried about the baby not growing well, I obviously cannot just forget the OB's worries about it. I asked around in a forum of pregnant and mommy PWD's, and was comforted by the fact that far from all had had big babies. Also, the fact that my now 6 months old niece was also estimated to be a bit too small, but came out at 52 cm and around 3,500 g at 41 weeks comforts me, as it makes me think that maybe it's just part of my genetic makeup (both my sister and I had similar lengths and weights, and none of us were born "on time", but a bit after our mom's due dates). Or maybe it's just because the little one is so active? ;-)
