My 4 month old baby was diagnosed with larangalmacia mildly as he has been a lot better he also has silent reflux dose this cause him to have a cough?

Silent reflux: His cough is more likely due to the acid from his reflux getting into to his lungs, rather than laryngomalacia.

Possibly: The laryngomalacia is just a floppy airway- the airway support hasn't developed well yet, so he makes a lot of noise with breathing. The reflux causes stomach fluids to come up the esophagus (swallowing tube) and causing irritation. That can cause coughing/choking problems. Hold your baby upright after feeds, burp frequently, and avoid overfeeding. Most babies grow out this in time.

Yes: Chest congestion, cough, and wheezing are likely to happen with minimal or no visible spitting-ups.

Yes: Most common associated symptoms related to feeding include regurgitation (ge reflux), emesis, cough, choking, and slow feedings. Infants with laryngomalacia may have a difficult time coordinating suck swallow breath sequence for feeding as a result of their airway obstruction and sometimes have aspiration problems.Treatment of ge reflux and thickening of feedings for aspiration often help.
