I like to get mom out of the cage first and put her into a tub that has air holes and a lid....fill it with enough water for her to soak but not enough for her to have to swim...water temperature should be 85 to 88 degrees, make sure you have the temps correct.
Once mom is soaking safely in the tub you are free to work with the babies without the worry that mom is watching you
After all babies are put into their holding tub, make sure to clean all of the mothers cage to remove the scent of her litter, fresh bedding and put mom back to rest in her cage.
This is just what I do....you probably already have a plan in place....just wanted to share information and opinion.
Take care and lets see some more pic's.
