Nutramigen formula is for infants that cannot tolerate other formulas. To help you with the vomiting here is a few pointers. The feeding position is important and should be almost a sitting up position when feeding her. Never lay the baby on her back right after eating because the acid from the stomach goes into the esophagus and causes pain. Raise the head of her crib to a 45-degree angle too so she is not flat on her back. Feeding her 5-6 times day will help. Hoped this helped.
oh and make sure you burp her before putting her to bed, keep her in a vertical position for at the very least15-20mins.
try soya milk formula and use the right amount of water for the scoops....I think 30ml water to one scoop of formula.
