How to quit breastfeeding?

Sophia • Baby boy born 11/22/19 TTC #2

I’m tired 😩

My LO is now 14 months and has been exclusively feeding from one breast 🥴 (My right boob just never turned on 🤷🏾‍♀️) I work full time from home and watch him all day. It’s exhausted having to breastfeed with his teeth scrapping my skin. But I don’t know how to quit because he still hasn’t transitioned to milk (we’ve tried cow, goat, almond and soy) and he relies on being breastfeed to sleep.

Anybody have tips on how to get baby off of me?!
