My son spits up after every nursing does he have a reflux problem?

Maybe reflux. A child who has always been spitty after each breastfeeding may have gastroesophageal reflux, especially if he is an otherwise normal child. Spitty babies need to be evaluated by a doctor to be sure there is not another problem causing spitting, such as some internal blockage or other medical condition. Treatment is available for reflux, so the doctor may prescribe some medication.
