I breastfeed my little son until 1 year old, when he was 4 months old, his growth line was dropped down from 5 to 3, at that moment, the doctor said that my son was adjusting his weight by himself, nothing to do and just monitor him, his growth line dropped down again from 3 to under 3 when he was 6 months old, I were worry too much at that moment, however, even he need to be consulted by doctor but the doctor never require me to stop breastfeeding, doctor said as long as his weight keeps to increase of the existing standard level and his developing are ok, then we don't need to worry about it too much! difference baby has difference situation. No 一本通書睇到老"....Breastfeeding is the best food to avoid baby getting allergy, good for their body. And breastfeeding will not feed baby overweight but healthy, overweight is not equal to have a good healthy...so don't give up! trust yourself!
