Ok, this may be long but trying not to drip feed.
DS is 13 weeks and has been FF for past 7 weeks. 7 weeks ago we went to the Dr as DS was screaming during every feed. No sick and ok weight gain. Dr gave us baby gaviscon for Silent Reflux but told us to try Dr Brown's bottles too.
So we start the Gaviscon and Dr Brown's bottles at the same time. Notice a big difference, stomach gurgling and screaming stops.
Unfortunately the Gaviscon made DS very very constipated - so we halved the dosage to every other bottle. This doesn't help constipation, so I wean off Gaviscon but stay on Dr Brown's bottles and DS is fine for a few weeks. This led me to believe that it was just wind that was bothering DS, and that the new bottles are helping. Go back to see Dr who agrees and we leave it at that and Dr pushes for no more gaviscon to be prescribed.
Now I think this was a big mistake on my part, because 6 weeks later we have all the original symptoms again. But now poor DS is being sick and choking in the middle of the night too. I feel so awful for stopping the gaviscon. One night he was choking so badly that it scared the living daylights out of me [sad} I have his bed nest elevated at the head end.
At his 8 week check Dr said that he was underweight. I've taken him to the Drs about choking and asked about it being silent reflux but I got fobbed off. I asked for more gaviscon but they were very very reluctant to prescribe it, as it sounded to them like "normal fussy baby behaviour".
so...fast forward to today. DS normally takes 6oz bottles every 2-3 hours, but in the last 2 weeks he will only take half the bottle and then want the other half an hour or so later. Today he can't even take half a bottle, he screams and screams and then falls asleep. He has not had a full bottle since 7 am this morning. Since midnight he has had around 8ozs, when normally he will have a 6oz bottle every 2-3hours.
The past few nights I have found his sleeping bag soaked with sick 
.
Should I go back to Drs and demand medication? Also should I look into Aptimel relfux formula? Is it prescription only as I have not seen it in shops.
TIA - sorry this is so long, I'm just so worried that there is something wrong and that the Drs think I'm a typical first time mum!
