Sarting a baby skin care line. What legal actions do I need to take?

What kind of legal steps and licensing do I need To Make and Sell Home Made Soaps?I am starting my own natural baby skin care line and am wondering if someone can help me out with what I need to do as far as licenses, Patents, Trademark?, etc to make sure I am doing everything legal and no one copies my brand. I will be making them at home myself. Does the FDA have any thing to do with this or the health department?
