If your baby's gastric reflux hasn't disappeared by his first birthday, tell your pediatrician. Ongoing reflux can lead to weight loss, dehydration, and other medical problems, and your pediatrician may recommend surgery to fix the problem. Avoid spreading germs by insisting that everyone in the house wash their hands thoroughly after using the bathroom or changing the baby's diaper. Keep your baby's hands as clean as possible, too. In addition to vomiting, a baby with a stomach virus may have diarrhea, loss of appetite, and fever.
Dehydration can be a serious problem for babies.
Once your baby has not vomited for two or three hours, start giving him 1 to 2 ounces of pediatric electrolyte solution every half hour to an hour. An electrolyte solution is generally easier than breast milk or formula for a baby to keep down. If your baby is still breastfeeding exclusively, you can give him the solution through a dropper or in a small cup to avoid nipple confusion . Then 30 minutes later, give him an ounce of breast milk or formula combined with an ounce of electrolyte solution. . After he's kept down two of the electrolyte and formula combination feedings without vomiting, use full-strength breast milk or formula, and increase the quantity of each feeding to 3 to 4 ounces every three or four hours.
