wonder how I hadn’t come across this sooner; it’s just perfect. My 3-week son had long and sharp nails when he was born, and immediately scratched his face pretty badly. I had purchased both nail clippers and files for babies and used them but still he was scratching his face. I even cut his finger with the nail clipper too... newborns' nails are so difficult to cut and too soft for nail files. After I read that mittens are not very good for sanitary reasons, I decided to buy this electric nail file, which I should have bought before his birth. I love the fact that it is battery powered and the rotating filing disc just makes my task a lot easier. The outcome is always neat, leaving my child’s digits looking well-manicure.
