My 7 month-old son has sounded very congested since birth. His breathing often sounds very nasally and loud, almost like a snorting type sound. It is worse when he is laying in the horizontal position, and he often snores at night. At times, he also seems to have a rattling sound in his chest. He doesn't act like this bothers him at all, and he never has a runny nose or anything. The doctor has checked his lungs at all of his check-ups and assures us that they sound great and that the rattling is not coming from his chest. She believes the congestion is somehow caused by reflux, and she prescribed Zantac at his 4 month check-up. Other than lessening his amount/frequency of spit-up, we didn't notice a difference with the Zantac. We also noticed during this time that he would sometimes have milk trickling out of his nose when he nursed. Not at every feeding, but about 2-3 times a week. We brought this up at his 6-month check-up, and the doctor still believed it could be linked to reflux. She prescribed a stronger type of reflux medicine, which he has been taking for 3 weeks now. Again, we are seeing no improvement in the nasal issues. Any other suggestions of what could be going on?
