Newborn fingernails and toenails are most often soft and flexible. However, if they are ragged or too long, they can hurt the baby or others. It is important to keep your baby's nails clean and trimmed. Newborns do not yet have control of their movements. They may scratch or claw at their face.
Baby's nails grow quickly, so you may have to cut the fingernails at least once a week. You may only need to cut the toenails a couple of times per month.
