I dont have any advice for you except talk to your mcn or doctor they might be able to help.

Are either you or your partner smokers?? Sounds a funny question I know but people who are exposed to smoke (second hand or not) are quite phlemy.

Your bubs is still quite young also so I know they can be snorty and gurgly as their body develops.

I dont know anything about reflux so I cant give you any answers.

Possibility he is teething early??

Like I said Im not sure so contact your mcn see what they say.
