A. Spit-up may appear curdled if your baby hasn't digested milk from feeding. This isn't always a health concern, but it's important to pay attention to any changes in your baby's spit-up. Talk to your baby's doctor if you are concerned about your baby's spit-up or have questions about healthy feeding alternatives.
