Hi J.-
Have you thought about pumping? Weening her from breast feeding while still giving her breast milk? I know some parents absolutely baulk at the idea of not breast feeding the natural way, but let's look at the positive side. She is still getting her mother's breast milk and you are getting a little more bed space. They (who are they anyway?) make bottle nipples that are so soft the transition shouldn't be too dramatic. They are tan colored, and I think made by either playtex or avent...Go to Target, squish a couple, try one or so of each and see which one the baby likes best. As far as not being in your bed, try her day time naps in her own crib. Then at night, she will adjust to being her own room. For that, there are fun items like the sound machines by homedics (Target) that make heartbeat sounds, rain, ocean waves, the rain forest, etc. AND, swaddle/bundle her up. Sometimes having the legs and body wrapped can make your baby feel like someone is right there/ more secure.
Good luck!
