My dd is five months old, and has been breastfed exclusively. She is a good weight, but her neck has rolls of skin, like a puppy. When she nurses or spits up, milk runs into her neck, and my dh and I wipe it out the best we can. Today we noticed a bad rash around her neck when we pulled all the skin back! I don't know how to keep this area completely dry so this won't happen. I don't know if/what I should put on her neck to help clear it up. Thanks for any advice.
