How do I dry up my milk?

Jordan

My son is 21 months old and the last month of breastfeeding, we only nursed one time right before bed every night. Well this will be 12 days in a row that he hasn’t asked for milkies so I guess we are done. 😭 My question is how do I get rid of my milk? My left breast is very small and doesn’t have much but my right is very big and feels like I have a good amount 😬
