i think my baby has reflux, what to do?

[sakoon]

for the last 4 weeks my baby has been really unsettled:
- cries a lot and does not sleep well
- will not lie flat, always cries
- he will go to sleep in my arms only in crunched position, as soon as i put him down on the bed, he cries
- when bottle feeding him, he stops and pushes his head back and cries
- he brings his legs up when he cries sometimes
- he vomits, sometimes small, sometimes a lot
- he does not drink the milk in one go, it drags on for 2 hours till his settled at every feed
- sometimes he would be lieing down playing and just pick him up and he starts crying

i thought it was just colic and givin infacol but does not work. i also thought its just a phase. My doctor just said thats part of being a baby and just have to put up with it

he has been on the NAN formula which is not thick and also been expressing and feeding.

i think he has reflux. what should i do from here?
