Thicken feed: Rice cereal may be added to the feeding to thicken the feed. This will help to reduce reflux. Slower feedings and burping the baby mid and after the feeding may be helpful. Avoid over feeding and hold the baby at an angle of 30-45 degrees. For forceful vomiting, red or green tinged vomitus or continued symptoms, please see your pediatrician.
