Is my baby “too big”?

Sometimes I’m approached by people in later pregnancy who have been told that their unborn baby is “too big”.

I talk to them about the accuracy of ultrasound growth scans (15-25% depending on which research you look at, which is a significant margin of error) and that abdominal palpation is not much better at predicting birth weight.

I talk to them about any medical issues they may have, for example pre-existing diabetes or gestational diabetes (the two are not the same) and their own feelings about the size of their baby. If you are told your baby is too big you may indeed be carrying a large healthy well-nourished baby, so fabulous, congratulations!
