Hi doctor, My daughter is 3 and a half months old. Her birth weight is 2.78 kg At one and a half months, her weight was 3.6 kg At two and a half months, her weight was 4.2 kg At 3 and a half months, her weight is 4.4 - only 200 gms has been increased in a month. Is it normal? Her urine outcome is more than 6 times a day and poops once in 5-6 days in average. For first 2 months, I was mixed feeding her. During 3rd month, I exclusively breastfed her but there is very little weight gain. I'm afraid whether I have low milk supply. Also I'm using nipple shield to feed her. Is that a reason for less weight gain?
