Is this likely a stomach bug?
Vomiting and loose stools that start around the same time are often caused by a virus, especially if your baby seems less interested in feeding or has been exposed to illness.

01
When a baby has vomiting with diarrhea
Baby vomiting and diarrhea often happen together with viral stomach illnesses, but they can also show up with feeding intolerance, reflux plus a separate stomach bug, or irritation after feeds. For infants and newborns, the biggest concern is how quickly fluid loss can add up. A focused assessment can help you sort through timing, feeding patterns, wet diapers, and other symptoms so you know what to watch closely.
02
What parents usually want to know first
Could feeding be making it worse?
If your baby vomits and has diarrhea after feeding, details like breastmilk or formula intake, recent changes, and whether symptoms happen between feedings can help narrow down what may be going on.
Are dehydration signs starting?
Fewer wet diapers, dry mouth, unusual sleepiness, or trouble keeping fluids down matter more than stool frequency alone. These are key details in deciding next steps.
03
Symptoms that help guide next steps
How long symptoms have lasted
Vomiting and diarrhea that started today may be managed differently than symptoms that have continued for 1 to 2 days or longer.
How often your baby is vomiting
A baby who keeps vomiting and has diarrhea may need closer attention than a baby who threw up once or twice but is still taking some fluids.
Changes in stool and behavior
Infant diarrhea and vomiting can look different depending on age. Loose stools, fussiness, low energy, fever, or worsening symptoms all help shape the guidance.
04

Frequently asked questions
What can cause baby vomiting and diarrhea at the same time?
Common causes include viral stomach illness, feeding intolerance, or irritation after feeds. In some babies, vomiting may already be happening between feedings and diarrhea starts separately. The pattern, timing, and your baby’s age all help clarify what is most likely.
Is newborn vomiting and diarrhea more concerning than in an older baby?
Yes. Newborns and young infants can become dehydrated more quickly, so vomiting with diarrhea deserves closer attention in this age group. Guidance should take age into account, along with feeding ability and wet diapers.
What if my baby vomits and has diarrhea after feeding?
That can happen with a stomach bug, but it can also relate to feeding volume, formula changes, or sensitivity to feeds. It helps to look at whether symptoms happen after every feeding, between feedings, or along with other signs like fever or low energy.
How do I know if my baby keeps vomiting and has diarrhea often enough to worry?
Frequency matters, but so does your baby’s overall condition. Repeated vomiting, trouble keeping fluids down, fewer wet diapers, unusual sleepiness, or symptoms getting worse quickly are more important than one isolated episode.
Can baby vomiting and loose stools happen without it being serious?
Yes. Some babies have mild, short-lived vomiting and loose stools and recover well with close monitoring. The key is watching hydration, energy level, and whether symptoms are improving rather than continuing or worsening.
