At my 33w4d ultrasound she was weighing in at 4lb 2oz. I realize ultrasounds aren't completely accurate, but it just seems small to me. Is this an average weight for this gestation? The tech wasn't concerned, but compared to other people it just seems so small! She has been measuring 1 week behind since 18 weeks, so I guess it is normal for her... What was yours around this time??
