First off, congratulations!
With babies running about in there, they'd be at risk of cannibalizing each other. Once mom finishes, I'd suggest placing a piece of bark or something in front of her and scootching her on with a pair of long tweezers or an artist's paintbrush (not the kind you paint your house with). Then you can just move her to another tank. I would NOT try this while she's still giving birth.
Once they molt and come off mom's back in a week or two, you can offer them small (pinhead) crickets or possibly baby roaches, if you have them. They shouldn't have any trouble tackling prey their own size or larger (though they may run away from it instead of attacking).
I also see at least two others that may pop soon -- may I suggest moving them to their own containers before they do so?
