My baby girl is 4 months old now, but she takes feed less than her age, only 60 ml every 2-2.5 hrs. At night she takes feed longer than 5 hours of gap. How to increase her hunger please suggest. At 3 months of her age her weight was 5.1 kg (Birth weight 2.4kg). Urine output - around 10 times a day, stool passes 2-3 times a day. I have heard the babies of her age take 120-150 ml milk but my girl is only taking 60 ml. I am concerned about her nutrition. She is on the complete formula milk_Dexolac. How to increase her hunger ? If I try to feed more, she just vomits all the milk. I don't want to force feed her.
