My newborn's nails are long. Should I cut them?

I only cut my newborn's nails when she was about 4 weeks old. Before that, I put on mittens for her so she wouldn't be able to scratch her face. The best time to cut your baby's nails are after a bath or when he is sleeping. http://sg.theasianparent.com/easy-tips-for-cutting-your-babys-nails/
