Vomiting is one of the most obvious signs in acid reflux in babies. Other symptoms are subtle and may be difficult to recognize. For example, if the baby has a cough that just won't seem to go away and he has difficulty breathing he may have acid reflux disease.
Symptoms like heartburn and abdominal pain are difficult to detect simply because the poor baby can't tell you what specifically is wrong. A sign of acid reflux in infants can include 'gas' and stomach discomfort. This will usually manifest itself with restlessness and crying, especially during and right after feedings.
The baby may also have difficulty eating. He may choke and cough while you are trying to feed him. These more subtle symptoms resemble colic and it is important to note that the two conditions may be related in some cases. Colic and acid reflux in infants often go hand in hand.
