Reflux in infants is a common issue, and usually resolves on its own. However, if your baby is exhibiting certain symptoms like blood in vomit, bile in vomit, excessive crying, difficulty breathing, or poor weight gain, it may be necessary to consult a doctor. There are some strategies that can help manage reflux, such as holding the baby upright after feeding, choosing a more easily digestible formula, thickening feedings with rice cereal, and offering smaller, more frequent feedings. These techniques may provide some relief, but it's important to monitor your baby's symptoms and seek medical advice if needed.
