That is probably one that you might want to put a post in the experts panel. It might be a difficult one as your daughter has reflux and its not as simple as a child with nothing wrong. Some babies can sence the mum being close and I have heard that it can make the reflux worse, but that may be an old wives tale too, thus why I would try and talk to a professional.
I have used the pat shh technique and it worked for us. You have to pat quite firmly though (not rough just firm to immitate the heartbeat). The first time that I succsfully did it I was patting for 1 hour. But this is not normal and I was doing it supervised by the sleep school. I found it usefull talking to the experts as I got strict perimeters to go by. That child that i did it for is now 2.5 and although he is not a great sleeper he does put himself to sleep- with a dummy!
Not sure if I have helped, but still let us know how you go. And good luck...
