She was in her own cage, but I'm thinking because she was in a tank right by the drier that she was stressed from the noise/vibration.

I just don't seem to have luck with babies this time around. A day later two more litters were born. One of them got their tank flooded 'cause the mom pushed the bedding up against the water bottle. No one died, thankfully, but the mom was sooooooo stressed out when we were changing the bedding.
