My Ds was born at 41 weeks weighing 5lbs 3oz despite a previous growth scan predicting a birth weight of between 6 and 7lbs. The GP has referred him to a paediatrician as he considers this birth weight to be 'abnormal'. He has continually gained weight since birth, never refuses feeds, seems alert and neither myself or my DH are big people (I was about 7.5 stone before I conceived). Just wondered if anyone out there has a similar experience and what the outcome was ? Getting a bit worried about the paed appointment as the gp mentioned cystic fibrosis. Sorry this is a bit long !
