Sounds big - not huge for a Western baby but that would still be considered on the large side. A baby over 4kg is regarded as ‘macrosomic’ (one in 10 babies in the US, so not all that rare there, maybe rarer here) hence possibly the ‘giant baby’ was a more literal description
-You could ask your own parents about your family’s birth weights - that could have a bearing on it even though on her side they’re low. However, usually small mother = small baby.
-A better nourished baby will be slightly bigger than if the mother smoked, ate badly, etc.
-Things like gestational diabetes can cause large babies, although she should have been screened for that.
- The estimation of a baby’s weight pre-birth is an art, not a science. I can’t remember the error rate they gave me, but I thought it was of the order of ±20%!!! It’s at least 10%.
-Caesarean might be recommended by your doctor depending on the circumstances.
Note: For (complete) pain management in a straightforward birth, an epidural is perfectly good for most women - you don’t need to have a Caesar just for that reason. A Caesarian, despite being routine nowadays, actually counts as major surgery, and the recovery time is maybe double that of a vaginal birth, if not longer.
As for the actual mixed race baby question, I don’t know if that has any specific impact. Good luck!
