The quick answer is probably not. Spitting up is unlikely to be a sign of allergy or intolerance to a particular formula. But you should try to figure out why she is spitting up. Here are some questions to ask yourself before discussing it at your newborn’s next check-up.
Is the spitting forceful?
Is the baby gulping so fast she is overgrazing and then vomiting?
Is there a lot of spit-up? Does it happen with every feeding?
Does she seem uncomfortable with feeding or when she spits up?
Some things your doctor would want to hear about immediately are: 1. Forceful vomiting with every attempted feed; 2. Discomfort with feeding or spitting; and 3. A decrease in the number of wet diapers over 24 hours (less than 5 in a baby that was previously having up to 7-8 diapers daily). If you observe any of these behaviors, make sure to tell your pediatrician right away.
