I'm back
Do you suspect his reflux is flaring from teething still? Does he have a lot of drool? I know in your other thread you mentioned that everything was ok until recently, so it may be that he needs some meds or change in diet if its intolerance related to get through this reflux flare. Just because he was med free and things were going ok doesnt mean that he wont need meds or a thickener for his feeds when circumstances change, yk? I would make an appointment with the doctor about it because it seems to be going on long enough to be more than just a short flare up of his reflux.
On a side note, I cant believe those doctors (actually I can, there are some horrible ones out there), honestly if he was diagnosed with reflux but didnt respond well to the meds but was still having problems, then I would think a change in meds would be the next step OR investigating the possibility that the reflux is being caused by intolerances. I would say babies grow out of spitting up, you know those happy spitters that dont have reflux...babies with reflux dont necessarily grow out of the reflux because its acid coming up that is irritating them, not just their formula/breastmilk, if that makes sense.
