This was perfect for filing down my 3 month old's nails. I was scared to use clippers on his tiny fingers, so thought I would try this. I was able to easily file the nails down quickly with the orange color attachment (there are different attachments for different ages/purposes). It is very gentle and does not hurt the baby's skin but is effective on the nails. The light on it is fairly useless though so I wouldn't try to use it at night or in a dark room. I have used it during daytime naps and it does not wake the baby up.
