Baby weight...

well with me they told me that my daughter was going to be close to 13lbs at birth and she came out weighing 6lbs 12oz.  But they did mine all by ultrasound.  I had riley one day before my due date. 

I actually work in x-ray so we get to take a peek every so often and I just had an ultrasound at 29 weeks and she weighed 3lbs. 5 oz. which is about 5 oz. over what "textbook" says I think.  My son was big though he was 8 12oz. and 1 week early so they said he would've been over 9 pounds.  You may just be having a big baby or the ultrasound may be off b/c I know the weight can fluxuate up to 1 pound more or less, I think.  I hope this helps but i wouldn't worry to much~
