My 3.5 month old baby is on formula milk due to some medical reasons of mine. She drinks only 60 ml every 2 to 2.5 hrs, she never drinks more than that. But before in her 2nd month she drinks 90 ml but after that it decreases. Also she vomits her whole intake milk sometimes from nose and mouth as well. Her birth weight was 2.39 kg and at 3 months old her weight was 5.1 kg... Her urine count is around 10 times a day (used to pee more before ( it reduces may be due to summer). She poops around 3-4 times a day (little runny with mucus). I am worried about her milk intake, is it sufficient for her ? is her weight gain okay ? My girl sleeps around 15-17 hrs. Kindly reply... Right now she is learning to roll over.
