I'm glad that she was ok Ken. What a most frightening thing to happen. Sounds like it something that does happen to some children. Now I'm scared...
Altho I am always on red alert with my 2 girls. How much can you do to make sure they are ok without going around the bend. I'm almost at the same point as your daughter is, I am always going to her crib to make sure she is breathing despite having a breathing monitor on her.
I hope she settles down and is able to get some proper rest and enjoy her baby.
Hugs to you all
