Hello. Congratulations on the brood.
Dont worry about anything, first off, the mother is naturally resistant to hunger whilst carrying the brood on her back. If it makes you feel more at ease by giving her some food, a head crushed feeder left near her hide would be fine. A free roaming stranger would just stress out her and her babies.
You dont have to do anything at all, literally. It would be best for the mother to be left alone until her kids start dismounting.
they usually dismount soon after their very first molt, which is a few days since birth.
So until they get off of mother's back, do nothing!
