It seems like my baby is spitting up a lot. Can spitting up affect my baby's growth?

Normal spitting up doesn't interfere with a baby's well-being. As long as your baby seems comfortable and is eating well and gaining weight, there's little cause for concern. If your baby is gaining weight, then he or she isn't being harmed by the calories lost through spitting up.

Keep in mind that it's easy to overestimate the amount your baby has spit up based on the size of a spit-up stain.
