No; the wonderful thing about these electric nail clippers is that they all come with a handy guide that tells you exactly which filing grits should and should not be used on your baby. Most of them come with up to six different types, so being able to distinguish between them is crucial. The filing grits that are clearly labeled as being suitable for your baby are designed to be super-soft and gentle to minimize any discomfort or irritation. The older the baby is, a corresponding filing grit may be used according to the product guidelines.
