is it okay to use nail cutter to cut baby nails   

The easiest way to cut a baby’s nails in the early days is to peel the ends off with your fingers. Baby’s fingernails are so soft that the excess will come away quickly. The best time to do this is right after a bath when the baby’s nails are the softest. Another safest way to clip away a newborn's nails is filing. Doctors recommend using an emery board (a thin piece of cardboard or foam sheet with emery paper stuck on it used for shaping fingernails) in the first few weeks of a new baby’s life because the nails are very delicate. You could also try using a pair of baby scissors or clippers made especially to use on tiny fingers. But for this method, you need to be very careful. The best time to do this is while the baby is sleeping.
