My baby girl is 4 months old and since she was 6 weeks old has only put on 100gms a week, The HCN keeps telling me that she should be putting on more but dosen't give me any advice on what I should do. I breast feed and have tried offering formular but bub is just not interested. I would rather just breast feed but feel that she isn't getting enough from me. I have also heard that the standard 150gms-200gms a week weight gain is based on bottle fed babies. can anyone tell me if this is true. or is there anyone out there who's bub has the same weight gain as mine?
