My daughter is 25 days old . She is doing spitting after feeding and sometimes doing vomiting at night. She is not taking burping . I m giving her vitamin D3 everyday 0.5ml once a day and colicaid for gas 5 drops after 4 hourly gap before 15 minutes of feeding. Yesterday's night she did yellowish vomit after that I have given Emeset4 drops. After 1 hour I fed her that time she was not able to take proper breathing. After 5 minutes she settled.she was crying when I feed her and most of the time she is sleeping and at night she is awake.
