Re: Babys head is too small?
I had this with my first, was told she was measuring small head at 20 week scan, then sent back at 22 weeks, still concern so again at 24weeks, this time the consultant told me that that he thought my baby had microcephaly (very small head) and I had to drive 100 miles to see a specialist immediatly who would advise as to whether to terminate. (my consultatnt was of the opinion that if she did have it he would strongly recommend termination due to basically no quality of live, ie unable to walk, feed self, basically to function). My mum drove me to the specialist, I was terrified and after about 5 hours they eventually said the didn't think it was microcephaly and that she was just a very small baby. Went through rest of pregnancy with various worries had to go for frequent doppler scans as they didnt think she was getting enough blood through the cord, worry was made worse as I have a brother with severe learning difficulties which were present from birth.
End result my daughter was born with quite a small head (great for delivery!) but not abnormal, she weighed 6lb 7oz, is now 8 and is at least 2 years ahead of her actual age in terms if reading/maths etc and is one of the brighest in her class, so they do get it wrong, as has been mentioned there can be a large variation in head measurments. Conversley my mother had no problems at all during pregnancy with my brother and yet he was born with a whole host of problems that were never detected. I would reasure your friend at this point as it is most likely just a small baby, does your friend have any problems in the family in terms of birth defects. I do think that they were just really overcautious with me because of my brother and that I was probably worried far more than was necessary. Hope this helps
