My baby keeps scratching his face leaving red scratch marks . I have trimmed and filed his nails but they are still sharp . Would like to ask what do you use to file and trim your babys nails so that they are not sharp ?

If your baby is still 0-3 months, let him wear a mitten even after cutting nails. After 3 months then take off the mittens, & let them explore/learn some motorskills.
