Nappy rash is a rash in the nappy area that often affects the skin of newborn babies. It is caused by prolonged exposure to a wet or dirty nappy.
If your baby gets nappy rash, you should change his nappy as often as possible (at least eight times per day), so his bottom stays as clean and dry as possible. You should also apply a product that absorbs damp and protects and soothes the skin in the nappy area. If symptoms persist, consult your doctor.
