Weaning from nursing

Hi! My son will be 2 in Feb. I have been nursing him his whole life. Any tips on how to start weaning? When I’m gone at night he will take a sippy cup from dad then let him rock him to sleep. But I can’t put him down for a nap, bed, etc. without him ripping my shirt off. He doesn’t nurse any other time besides morning nap and bed. Any tips from anyone who has been through something similar would be great! I feel like he’s just going to scream and cry and non of us will ever sleep again lol
