soaked bedding -babies 13 days old -help?!

[kmknits]

Hi -I am hoping someone with breeding experience can help me with some advice here -I've been posting in the groups about my non planned rescue momma and litter...babies are now 13 days old and momma moved the nest over night to under the water bottle -as you can imagine it has then drained out into the bedding -soaking the momma and babies. Since their eyes are not open yet I haven't touched them or made any changes in their habitat, so what should I do at this point? she is still laying in the wet bedding with them all and I don't want to upset her, nor have any of them get sick? I have no idea what my best choice is right now...do I remove them all and change the bedding? If so, do I move them together or in separate bins? Will the bedding dry on its own? Will she come to her senses and move them all -I see no signs of that at this point. I moved the water bottle to the other end of the cage, but don't know how to lower it enough so that the babies could reach it without her doing the same thing with bedding again? HELP?!?
