Bed #1: Her crib. To be honest, I'm not comfortable with her sleeping in a different bedroom from me. I know at some point I will be, but that point isn't here yet. She's slept in it once when her dad was in there working overnight. This didn't bother me because he was in the room. Since then and before then it hasn't happened because we haven't been in the room (although the hubby's tried to talk me into it a few times).
Bed #3: Mommy and Daddy's bed. This is her favorite bed, but mainly when she's on top of mommy or daddy. This adds to my fears. This worries me because I worry that something could happen to her if she were to fall off of mommy or daddy. Worry was the reason I bought the fourth bed.
Bed #4: Her Snuggle Nest. The snuggle nest is the best of both worlds. It's a co-sleeper that is on her parents' bed. She has her own space clearly marked out on our bed. Not only does it have her own space, it also plays a lullaby, womb noise, and has a night light. This co-sleeper cannot be done if you have a bed smaller than a queen size though. To be honest, even on our queen size the husband complains about not having enough room. But I'd trade us being a little uncomfortable for some peace of mind.
She sleeps well in the last three beds. Our little bundle starts out in #2 or #4. Typically after her early morning feeding, she snuggles with mommy for an hour or so until we get out of bed. Ultimately (when she's older) she'll sleep in her crib, but until then it's whatever makes her happy.
