racecar 555: It may mean absolutely nothing....is this your friend's first baby????
If it is, I can tell you that I didn't feel any movements until about the 5 or 6th month, and it was my first.
They say that with the first baby, you really don't feel anything much until quite later on..because basically you don't know what to look for...because you've never felt it before...alot of times a little 'flutter' or wave you may not even feel, or you may think is gas, or your tummy rumbling..etcetc..
And about being a big baby...I will tell you that u/s do NOT give a very accurate estimate of weight.
I was told at 30 weeks that my baby was at 4lbs, then at the later u/s I was told he was 8 lbs...I was getting freaked out because for me..that was a big baby....
Do you know what he turned out to be on delivery?
6 lbs. 11 oz....yes...they were 2 lbs. over what the weight really was...
So I don't give any thought to weight when someone tells me from a u/s.
Also, has your friend been checked for Gestational Diabetes?
Probably nothing is wrong...but if she is overly worried and all consumed with this, then maybe she should call her ob and talk about it...
