Noelle - I'm so sorry to hear she fell. I would have been beside myself. I still remember the first time DD rolled off the bed. She was 8 months old and much more sturdy, but I still felt terrible. I'm glad your little sweetie seems fine.
What is a sleep nest?
Yeah... was she crying when you found her, and did she calm down quickly? That's how I gage an "injury" around here. If they calm down pretty much instantly then they really are just fine! I think all of my babies have had at least one "incident" similar to that at some point. Poor Aidan actually rolled out of the bed and hit the wall first before sliding down to the ground once... but he calmed down instantly when I picked him up - he was completely fine. These little babies, while still fragile, really are quite hardy too.
