my baby is one month old. she is vomiting curdled milk sometime after feeding. what is the reason.

A. Babyhug# Babies' spit-up becomes curdled when milk from breastfeeding or formula mixes with the acidic stomach fluid. Time also plays a role here. Immediate spit-up after feeding will probably look like regular milk. If your little one spits up after some time as passed, it's more likely to look curdled milk
