Hi there Jen,
The reflux could be causing some night time problems, it did with Red in those first few weeks. Try propping the head end of his crib/ moses basket up, just create a small incline, then roll up another blanket and curl it round to create a little resting place for him - so ensure he doesn't slip down. Are you swaddling? Reflux babies do tend to be more touchy and Red still cannot sleep with out his swaddle - the tighter the better. Red uses a paci - again it helps loads with the reflux, i think if you are sensible with its use then it won't be too much of a problem later - but right now i would use it if it works now and deal with the consequences when things are a bit smoother later on!!
Red would wake in the night with tummy pain and gas - is he ok in that department? Are you planning to take him to the docs about the reflux?
