Breast milk is GREAT for nappy rash (or so I've found). I express some at the end of a feed then either dunk a bit of cloth in it and wipe Caty's butt or I drip it onto her butt. I let it air dry a little then chuck her (cloth) nappy on. Apparantly the thicker the breast milk, the better it is for healing stuff. Also good for gunky baby eyes.
