Newborn fingernails and toenails are usually soft and flexible, but can cause injuries to the infant. Newborn infants do not yet have control of their arm, hand, finger, leg, or foot movements, and may inadvertently claw at their face. Nails that are ragged or extend beyond the tip of the finger can cause scratches to the face and eyes.

Clean the baby's hands, feet, and nails during regular bathing. Trim nails carefully with baby nail scissors that have blunt rounded tips or baby nail clippers. (Do NOT use adult-sized nail clippers -- you may accidentally clip the tip of the baby's finger or toe instead of the nail.)

Use a soft emery board to keep the nails smooth and prevent injuries. Since baby's nails grow pretty quickly, 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.
