If your baby is projectile vomiting and having diarrhea, it can be hard to tell whether this is a stomach bug, feeding-related irritation, or a sign they need urgent care. Get clear, personalized guidance based on your baby’s age, symptoms, and what happened after feeding.
We’ll help you understand what symptoms matter most right now, when dehydration or another urgent issue may be a concern, and what next steps may make sense for your baby.
Baby projectile vomiting and diarrhea can happen for different reasons, and the timing matters. Some babies have forceful vomiting and loose stools during a viral illness. Others may vomit and have diarrhea after feeding because of feeding intolerance, reflux, or irritation in the stomach and intestines. In newborns and young infants, repeated projectile vomiting can sometimes point to a more serious problem, especially if your baby seems weak, is not keeping feeds down, has fewer wet diapers, or the vomit is green or bloody. This page is designed to help parents sort through infant projectile vomiting with diarrhea in a calm, practical way.
Watch for fewer wet diapers, a dry mouth, no tears when crying, unusual sleepiness, or a sunken soft spot. Projectile vomiting and diarrhea in babies can lead to fluid loss faster than many parents expect.
Green vomit, blood in vomit, or repeated forceful vomiting after most feeds should not be ignored. Newborn projectile vomiting and diarrhea can need prompt medical evaluation when vomiting is persistent or severe.
If your baby is hard to wake, very floppy, unusually irritable, breathing differently, or seems to be in pain, those symptoms matter as much as the vomiting and diarrhea themselves.
Infant vomiting and diarrhea after feeding may happen with overfeeding, feeding intolerance, reflux, or an illness that is making the stomach more sensitive. The amount, force, and frequency all help clarify what may be going on.

Baby vomiting and diarrhea when to worry depends on age, hydration, and how the vomit looks.

It can. Some babies have vomiting and loose stools related to formula intolerance, cow’s milk protein issues, or feeding volume problems. But forceful vomiting after feeding can also happen with reflux or illness, so the full symptom pattern matters.
Projectile vomiting usually means the vomit is forceful and shoots out rather than simply dribbling from the mouth like spit-up. If your baby has repeated forceful vomiting with diarrhea, especially after most feeds, it is worth assessing more closely.
Often, yes. Newborns have less fluid reserve and can get dehydrated more quickly. Repeated projectile vomiting in a newborn should be taken seriously, particularly if there is poor feeding, fewer wet diapers, unusual sleepiness, or green vomit.
