Is she in your room? My first son was in our room for 6 months, my second for about a year (we were not ready to have them share, but we were ready to have him out). I found that my older boy slept better on his own--I think he could smell mommy and figured he may as well be nursing in his sleep, and he could hear every little sound we made. Thankfully, they were both generally great sleepers. I always have had some kind of "white" noise in their room, even if it is just a fan or humidifier. Before my older one started getting up and turning it off, we played a quiet CD on repeat until he was pretty soundly asleep--I think it was a Rock-a-Bye Baby CD, so very mellow.
