I’ve tried so many things to trim my 5 week old babies nails. We have used “infant friendly” trimmers and clippers and we have still managed to cut him. We were told to bite them but then they become like little serrated knives. He was scratching himself constantly until we found this amazing invention! Only $5 more than the silly clippers we bought and it’s perfect! Gentle, easy and it really works. He hasn’t scratched himself since.
