Hello Doctors, My son born on 10th APR-2016 with 1.96 KG with PRE-TERM (34 Weeks 6 days) and currently he is with weight of 3.8 Kg but he is continuously taking the FORMULA MILK (Similac Advance 1) only because my wife is not getting the breast milk like very rarely she can get breast milk and she is trying to give parallel but we are really worrying because as we are seeing through out the day he is feeding with formula milk only. Please suggest is there any harm? And what to do this conditions since if he is having hungry he will cry lot and after formula milk feeding he is OK. And he is more active like hitting through his legs and hands and keep on looking the persons and laughing and responding if we tell some thing. Suggest please for the further way forward. Thanking you in advance!
