I wouldn't worry about the borax harming your little ones, as it is extremely benign as chemicals go. I lived in the FFZ of Boron, California for most of my life, downwind from the worlds largest open pit borax mine. Not only did I not suffer any ill effects (I spent several college summers working at the mine, comming home coated with the dust, etc.) but my furries LOOOVVVEEEED to dig in the borax/sand dunes directly east of the pit, no harm at all. What your little ones will pick on their feet won't harm them a bit, assuming it is a true borax dust, and doesn't have more harmful chemicals in it as well. I'd read the label and go from there.
