In children, GERD symptoms will vary based on their age. Young children may experience spitting up, vomiting, and coughing (which are symptoms shared with reflux). In a small number of infants, symptoms may be more serious. Examples of these problems can include:
Poor growth due to an inability to hold down enough food
Irritability or refusing to feed due to pain
Blood loss from acid burning the esophagus
Breathing problems.
 
For older children, GERD symptoms can be similar to those experienced by adults. In these cases, the most common symptom is heartburn. The pain or discomfort caused by heartburn usually starts in the middle of the chest and can move up through the throat. With GERD, heartburn can be frequent, constant, and/or severe.
 
Other common symptoms of GERD in children may include:
Sensation of food stuck in the throat
Feeling like they are choking or the throat is tight
Acidic or sour taste in the mouth (acid indigestion)
Difficult or painful swallowing
Chest pain.
