How can you accurately predict the weight of your unborn baby?
📸
We know that ultrasound measurements have a +/- margin of 15% error.
This means your baby could weigh anywhere between 85% and 115% of the estimated fetal weight (EFW) -- that's if they fall into that weight range at all.
We also know that only 81% of scans carried out between 34 and 37 weeks gestation fell within that accepted 15% margin of error.
With less than a third getting as close as 2%.
Considering how many recommendations are made, how many interventions are pushed as necessary, and how many "big babies" are blamed, based almost purely on EFW, it's a little concerning how inaccurate that data is.
So, how can we accurately predict bub's weight?
Place them on a scale once they are born.
