#asktheexperts hello doctor, how to know if milk supply is enough for baby? My baby is 5 months 14 days old, he is exclusively on breastfeeding and his pee count is good above 8 to 10 per day. But his weight is not gaining much. His current weight is 5.28 Kg , birth weight was 2.72 Kg. He gained only 140 gms last month. I am really worried about his poor weight gain , otherwise he is active playing ,pee/ poop is fine. what could be reason for slow weight gain?
