My daughter grunted all night long. She also would sometimes pant like a puppy dog..too weird :) She slept in a bassinet next to my side of the bed. It drove me kinda nuts, but eventually I got used to it.
I think it's pretty normal.
I just dealt with it until I moved my daughter to her crib a little after 4 months.
Oddly enough, the first few night after moving her were the WORST nights of sleep I had. It was almost too quiet in my room and I kept waking up thinking there was something wrong with her. I got over that pretty quickly though LOL
Sorry I don't have any advice. Do know that you will eventually get a good night's sleep, I promise :)
