we used a dummy very early on too.have you tried just using it to soothe her & taking it out before she actually falls asleep?we used to do that with our LO when she was too small to self-soothe (she is now ADDICTED to sucking her fingers!!!!no more dummy-her choice!) if she was crying (& in need of sucking) we would give her the dummy,but would take it out once she calmed abit but before she was falling asleep.it worked for us, but then we didn't have reflux issues, so maybe that would change things?
