GERD happens because the circular band of muscle that acts as a valve between the esophagus and the stomach is still immature in babies and let the acidic stomach contents regurgitate back into the esophagus, which cause pain. Thus, babies just keep crying for long periods of time and are often misdiagnosed as ‘colic’ and the real reason that is hurting them is left untreated. Babies may also spit up or vomit milk due to pain or make jerky movements such as pulling up the legs or arching the back. They may also take wet burps frequently or make gagging noises.

To ease GERD, make feedings more frequent and give lesser amount at a time. This will stimulate the production of saliva that neutralizes stomach acid and lubricates the lining of esophagus. Holding the baby upright for about after half an hour after the feeding prevents the stomach content from coming up. Breast milk is digested more easily than formula, so if possible breastfeed the baby. However, if baby is not gaining weight or not getting enough sleep due to pain, doctors may prescribe medications that stop the production of stomach acid. It usually subsides around 7 months as babies spend most of their time upright from that age.
