DS 11 weeks has had problems with wind and possetting/bringing up milk since early weeks (not first week, but soon after): on bad days he will bring up milk occasionally (or today almost constantly) for 2-3 hours between feeds, longer at night.
For a while he was regularly taking 90 minutes to wind at night and I got a bit despairing (for him and me as was shattered), but doubled Infacol dose and it seemed to subside for a couple of weeks. I stepped back the Infacolband it has got worse again, and now I feel there is no noticeable benefit when I do use it, though this might be because I'm not using it for every feed (prob about half of feeds).
A while ago I noticed he occasionally made a sort of coughing noise sometimes (similar to the noise my nephew made when he had an allergic reaction to peanuts). And a couple of times I thought I heard what sounded like liquid rising up and down his throat. Twice over the weekend he woke himself up doing that barking cough and with what sounded like a strong version of that liquid(?) rising up and down his throat. He was very distressed (which oddly he often isn't) and possetted/sicked up some "milk" (it was on sheets etc so couldn't tell how much really).
After a really awful day for the poor mite today I'm again thinking I should go to the doctor about this. Before I go though are there other things I can and should try? And has anybody had similar experiences to draw on so I can have a more informed talk with GP? I've mentioned this to HVs and GPs both when he had possible illness and at 7 week check and advice seemed primarily to ride it out. I don't rush to doctors usually but apart from his discomfort I am emotionally a bit shattered after today, on top of all the extra and longer night wakings (and we have a toddler).
He is BF and seems to be putting on weight well. Oddly his most reliably "comfortable" feed of the day is usually the 6-7pm feed fest after bathtime.
