Nail care

Ok guys, I have trouble with baby’s nails. He’s 14 weeks and give me a hard time with doing his nails, especially his toes. Even when he’s asleep he jerks away from me. Because of this I’m afraid to cut them with clippers (even the safely ones). I’ve been trying to just file them down with a regular nail file but oh my goodness it takes forever especially with how he jerks away, flails his arms, wants to play, or hold onto things. Any suggestions on what I can do?
