Manage infant vomiting, diarrhea, and stomach bugs safely
5
Gastroenteritis (stomach bugs) in infants is most commonly caused by rotavirus or norovirus. The primary danger is dehydration, not the infection itself. Continue breastfeeding or formula feeding through the illness -- do not withhold feeds. For babies over 6 months showing signs of dehydration, an oral rehydration solution (such as Pedialyte) can supplement regular feeds as directed by your pediatrician.
Signs of Dehydration to Watch For
- Fewer than 4 wet diapers in 24 hours
- No tears when crying
- Sunken fontanelle (soft spot on top of the head)
- Dry mouth and lips
- Unusual drowsiness or irritability
When to Seek Immediate Medical Care
- Blood or bile (green color) in the vomit
- Vomiting every feed for more than 8-12 hours
- Signs of moderate to severe dehydration (listed above)
- High fever combined with vomiting and diarrhea
- Baby younger than 3 months with any vomiting and diarrhea
Tips
- Offer smaller, more frequent feeds rather than large volumes at once
- Do not give anti-diarrheal medications (like Imodium) to infants -- they are not safe for young children
- The rotavirus vaccine (given at 2, 4, and sometimes 6 months) significantly reduces the severity of rotavirus gastroenteritis
- Wash hands thoroughly after diaper changes to prevent household spread
- Consult your pediatrician before making any changes to your baby's feeding routine during illness
