If your daughter has recently started inhaled antibiotics such as Pulmozyme or TOBI, then that could most definately be why her voice is raspy. When I started both of these, mine was that way & it did lessen quite a bit over time.It also may be par for the course to have a raspy voice, next time you take her to the Dr, (or before if it's really bothering you), ask the Dr what they think is the cause.
