I was told at my prenatal class to avoid nut oils, and any fragrances (I think even pure essential oils). She suggested olive oil or grapeseed oil. They just soak in, and baby is so much more sensitive to any of the "extras" in most commercial lotions and creams.
And as for powder, of course, no talc, but just plan cornstarch - no J&J -type, which is basically cornstarch, plus who knows what...Actually, she said cornstarch is great for massages instead of oil (she's also a RMT), and that for changes, unless baby needs a barrier cream to protect an existing rash, to avoid creams and powders altogether.
And don't forget, after baby is born, just rub in the vernix around the creases - the best moisturizer!
