My LO has reflux pretty bad (as you know) & before we got his meds sorted, he really didn't like bedtime, he'd sleep for a while but always wake. Its best to get LO used to falling asleep by herself in the cot, not on the boob or she will want that every time she is tired, rather than just when hungry. LO's get into a better sleep about 10 mins into their sleep, so if you really cant get LO to sleep in cot & your rocking her, or whatever, wait 10mins after she drifts off til u move her, a good trick I used was to put my hand over LO's side of face while he was sleeping & keep it on while I lift him into cot & very (annoyingly) slowly lifted it off. Try the re-settling techniques for if LO wakes again....stroking face, comfort her, but without lifting her. if she's hysterical, lift her &, soothe her for 5/10mins, place back in cot & keep doing that, trust me, it works. They need to be in their cot as much as poss, they wont be in cot as much as with mum, but its still a major thing for them to get used to, put LO in cot if your doing the washing/housework, rather than in her seat, she'll eventually get used to it & it wont be as strange for night time.
Its so difficult when sleep is messed up, esp when we've been running around all day. I suppose before we have our LO's we dont truely believe ppl when they say...wait til you get the sleepless nights & crying, and u think pahh i'll cope. Sad thing is, most of us dont, so dont worry, we all go thro it & it'll sort itself out.....I promise!!! Stay strong your doing brilliantly
