please note that the weight gain of your baby is fine. normally birth weight doubles by the age of 6 months which i think it has. as for 7-1/2 months of age the weight is only a very little bit lesser probably because of reflux issues. also babies pass stools either 10 to 15 times a day or once in two to three days so i do not think there is constipation. i feel that if the baby had any major problems then the child will not be able to become double of birth weight by 7 months of age. according to me the child is having a fair amount of weight gain which is slightly on the lower side probably due to the reflux which will go away eventually with age. also you can give multivitamins and calcium supplements to help the baby. also give mashed foods along with breast milk to the baby. for further information consult a paediatrician online --> <link>
though my baby is exclusively breastfed why does he fail to thrive?
