Babies tend to scratch mom's breast and their own faces when they are brand new. In THE OLD DAYS, we had sleeves with pull over cuffs to cover the hands so they could not scratch. By the time they are finding their thumbs and fingers the nails are no longer a problem. I wish I had known how soft the nails were and how the tip of the finger looks just like the nail. I know, my son will be in therapy for life for that one. (JOKE)
