My 8 week old DS is making very weird grunting noises, mostly at night - and also sounds like he's (deeply) clearing his throat. I did use to think it might be reflux, but he doesn't vomit and he's not in discomfort - he still sleeps - but it's just very noisy. Is he congested? Would I see it in his nose? (It's clear). He snores sometimes when he's upright in the sling...
Any thoughts as to what it is, and how to reduce it?
