What are symptoms of acid reflux in babies?is it hereditary?

Talk with your doc.: If a young baby cries as if in pain after eating - or if she cries in pain when you put her down, she may be having reflux. In reflux, food (i.e., breast milk or formula) sloshes up from the stomach into the esophagus. But it can be hard to know. So do talk with your baby's health care provider. In the meantime, hold her upright (sitting up or inclined) after eating and see if this helps.
