I stayed up in case she had more, but that was all. I went to bed at 1:30 am and was awakened by commotion! Puppy crying! I threw off the covers and ran into the living room, picked up the top of the crate and...only one puppy! Ginger came from behind me and ran into the crate! "Where's your baby?" I asked her. She ran out and over to the basket with the stuffed animal toys...there it was, all tucked in! So, I retrieved it and put it back into the crate and she cuddled them again.
We are keeping all warm with a "snugglesafe" heatpad under the bedding.
I closed the crate after that and went back to bed. (I also gave her the stuffed animal she had tucked around the baby).
Looks like we have two little girls! More details (markings) to follow.
