If your child or toddler has a stomach bug with vomiting and diarrhea, get clear, parent-friendly guidance on what to watch, how to support fluids, and when symptoms may need medical care.
Share what started first, how symptoms are happening now, and a few key details to get personalized guidance for a child, toddler, or baby with a stomach virus.
A stomach bug, also called viral gastroenteritis or a stomach virus, commonly causes vomiting and diarrhea in kids. Symptoms often come on quickly and can leave children tired, uncomfortable, and at risk for dehydration. For many children, the main focus is replacing fluids in small, steady amounts and watching for signs that they are getting worse instead of better. Because babies, toddlers, and younger children can lose fluids faster, it helps to look at the full picture: how often they are vomiting, how frequent the diarrhea is, whether they can keep fluids down, and how alert they seem.
Vomiting from a stomach bug often improves within about 24 hours, while diarrhea can last several days. Some children feel better quickly, but loose stools may continue after vomiting stops.
Offer small sips of fluid often, especially after vomiting or diarrhea. If your child wants to eat, start with simple foods and avoid forcing large amounts too soon.
Call a medical professional promptly if your child seems dehydrated, is hard to wake, has severe belly pain, has blood in vomit or stool, or cannot keep any fluids down.
A baby with fewer wet diapers or an older child who is peeing much less than usual may be losing more fluid than they are taking in.
A dry mouth, crying without tears, or acting much more tired and less interactive than usual can be warning signs.
If even tiny sips keep coming back up, it may be hard for your child to rehydrate at home without more support.
Baby stomach bug vomiting and diarrhea needs closer attention because infants can dehydrate faster. Feeding, wet diapers, and alertness matter a lot.
A stomach bug vomiting and diarrhea toddler may resist drinking, making small frequent sips especially important. Energy level and urine output are useful clues.
Older kids can often tell you more about nausea, belly pain, and thirst. Even so, frequent vomiting and diarrhea can still lead to dehydration quickly.
Vomiting often improves within about a day, while diarrhea may last several days and sometimes up to a week. If symptoms are getting worse, not improving, or your child cannot stay hydrated, seek medical advice.
Focus on fluids first. Offer small, frequent sips rather than large drinks. If your child wants food, start gently. Watch for dehydration, worsening lethargy, severe pain, or blood in vomit or stool.
It can be, because babies and toddlers can lose fluids faster. A baby or toddler with ongoing vomiting and diarrhea should be watched closely for fewer wet diapers, dry mouth, unusual sleepiness, or trouble keeping fluids down.
Get medical help sooner if your child is hard to wake, has signs of dehydration, severe or worsening belly pain, trouble breathing, blood in vomit or stool, a very high fever, or repeated vomiting that prevents drinking.
