L.,
We liked the Johnson and Johnson Vapo Bath - there's a generic brand too. It's a bath "bubble" that you add and it has some menthol to help open them up. Or try taking a shower with her before bedtime to see if you can sit in the steam for awhile to help loosen things up before bed. (If it seems like congestion.)
It sounds like you're doing everything right, just hang in there. I agree with a prior post that if it seems worse at night, see if you can add a pillow UNDER her mattress to give her crib a little more of an incline. We did this plus rolled up receiving blankets to "wedge" our child on either side so she wouldn't slide. You could put her to sleep in a baby seat or car seat for a few nights too. This was recommended to us when our baby had reflux.
Best of luck!
