My baby vomits out after feeding. One day can vomit about 2 - 3 times.. but other than that, she is still active, pee and poo as per normal. Is there cause of concern? I have already reduced the amount of milk from 110ml to 90ml, and increase from 6 feedings to 8 feedings per day. Also, i carry her upright after each feeding and place on the rocking chair (not rocking) at 45 degree angle.. not sure what else i need to do, should i bring her to the doctor instead?
