A.,
First of all, yes we have introduced so many extra chemicals into our lives that could possibly be causing extra respiratory problems in our children. But, isn't it interesting how it is always those who have something to sell you who will tell you to ignore the advice of your doctor?
Both my children have asthma. My daughter had RSV at 3 mos and was prescribed albuteral and pulmicort. We only used the pulmicort 2-3 times a day, not with every nebulizer treatment. My son was born 15 weeks early, so with under-developed lungs it was pretty much a given he was going to have respiratory problems.
What I did with them both, was hold them upright, and sing soft, calming songs in their ears while the nebulizer was doing it's thing. The machine is loud, which can be a bit scary, and they are being held down, which no one likes! You are right in that the mask doesn't have to be directly on her face to get the medicine into her lungs, and sometimes, when she cries, it enables the medicine to get deeper, as heart-wrenching as it is for us mommies to witness! Another thing my Mom, a neonatal intensive care RN, told me, once you have gotten the nasties loose with the neb, you need to knock it out, which we would accomplish by coughing. She got me one of those things they use to hack on babies backs when they're born, but she said the heel of your palm works, too. Just place the baby face down on your thighs at a slight downward angle and firmly tap on her back, rotate and do the same to her sides and her chest.
Also, is she gurgling or grunting when she is on her back? Grunts could be a sign she is having difficulty breathing I have asthma, and cannot sleep flat, I use AT LEAST 2 pillows to elevate my chest and head (and I still sleep with my mouth wide open because I cannot breathe!)
And don't worry about damage, it's not like she's going to be huffing it constantly every day. My kids only use it when they need it, which is less often than I do, I control their triggers and because I have asthma have a good handle on when the nebulizer or inhaler is really needed. We haven't needed to go to the emergency room for it yet (knock on wood!) With your history, you'll be more cautious and have an open eye, too. Besides, I'D rather have a breathing child (and with a son who spent 6 weeks on various ventilator in NICU, I know of which I speak)
Good luck to you and your little pumpkin!
