I’m tired of breastfeeding

S

He’s 19 months, he doesn’t sleep through the night. He always wants to be on my boob. I’m tired. I want to sleep a full night. I want to get some shit done during the day without having to stop and put him on me because he won’t stop crying. He’s not a fan of any other milk. He’ll drink other kinds occasionally but not when he wants to sleep. I have to nurse in order for him to fall asleep. What can I do to stop milk production??? I’m desperate!
