About the mother with a nipple crack: Many years ago I used UV lightsource for sore nipples (when you could use a sunlamp). Mine was a lab. UV lamp that my husband brought home from his lab - I could get the wavelength info from him. Before all of the moist wound healing stuff became the in thing UV light always seemed to be very helpful for the mothers who tried it. Unless the mother in question knows that her skin condition gets worse in the sun it might be worth a try. The hairdryer is currently not recommended by the experts. Sarah Barnett Bronx, NY
