My son was diagnosed with RSV last December when he was 18 months old. He was on 4x a day treatments forever! Everytime the weather got cold and everytime he got sick, we were back on neb treatments. They started him on Pulmicort in April (after he got the roto virus which also aggrivated it) so he had 2 Pulmicort/Albuterol treatments and 2 plain Albuterol treatments a day for awhile. Finally they put him on Singulair (which, for him, is a powder we put in applesauce) and that did the trick. Now, as soon as he gets a runny nose we give him Singulair and Pulmicort before he goes to bed. This helps him get over the cold in 3 days rather than 3 months like last winter. It was a tough 7 months for us, trying to fit in all the treatments, but he was never so bad to be hospitalized.
About the treatments. After the first 2 days, he didn't even care. We put the TV on and watched whatever he wanted until it was done. We took him on vacation with them and my parents even had him overnight a few times with them. It just becomes part of the routine. Now he "helps" us squeeze the medicine in the chamber and holds the mask when it falls. While it's a pain, the treatments do get easier.
Good luck. I hope it clears up faster than ours did!
