Shell's babies

I'm worried about Shell's litter. She had 3 babies that were born yesterday, and today I found one baby out of the nest on 2 occasions. They were different babies, and it doesn't appear that Shell was throwing them out. Shell is a funny mom. She either does really well with her litters or really badly. It appears this litter is going badly. She spent part of the day acting unsettled and not wanting to go back into her hut, but I also saw her feeding her babies a few times. Right now, all I can do is hope that she settles in and that she has milk.
