QUESTION: "I was wanting to know if crystals can be used with new born babies, or with expectant mothers?"
MY ANSWER: Crystals and stones certainly can be used with new born babies or expectant mothers. In these sensitive groups, it is particularly important to pay attention to safety. You need to ensure that babies or small children can't eat the crystals - securing them somehow, perhaps in a medicine bag or small pillow case might do it, but I can't say I'm very familiar with how to keep things out of children's mouths. For the babies and expectant mothers, avoiding potentially toxic stones (handling the dust, inhaling it, etc.) is also critical. I have an article on potentially toxic stones with tips on using stones safely that may be of some help. Other than that, I see no reason you can't use crystals and stones and their energies for babies or expectant mothers as you would other people.
