We always use Vick's rub at our house and it helps a bunch. If you have a vaporizer you might also try that. I know the aspirator seems like torture, but it does get the gook out!! I'm sure you could also use a little bit of infant decongestant without too much worry also.
Good luck--it's tough having a stuffy nose when you don't know how to blow it yet!
