Ds is a very noisy sleeper, he needs his adnoids sp? taken out. Dp had to aswell but not till he was 4. Were also going to wait until proboly just before preschool. The only way we found out it was the same thing because when we went to our gp ds was asleep in the pram and gp commented on it. Im not saying that what she has lol just that make sure she doesnt have any underlying problems :-) Good luck and buy some earplugs lol
