My ds is 8 weeks old and his weight is steadily increasing but not staying within the same centile, in fact he has dropped down 3 centiles since he was born. While I am not worried about his feeding and think he is healthy I am obviously a little concerned. As he is bf am wondering if finding a bf groeth chart would be of use - hv said they are not allowed to give us them. Is there a big difference between the two and where can i get hold of one?
