What causes loud quacking noises from an infant?
Patient: My 8 week old had an episode where he made this loud quacking noise turned red and started foaming and drooling from the mouth. After I pounded on his back his color came back but was lethargic and sleepy for a few seconds afterwards. What could have caused this? Reflux or seizure? Doctor: Hi...by what you quote I feel that it could be a seizure as 1st possibility and GER as second possibility. I suggest you take him to a pediatrician and get him evaluated.regards - Dr. Sumanth
