Weaning— where to start?!

Rachel

I’m 30 weeks pregnant and my 15 month old still nurses. It’s getting to the point where it’s difficult for me to maneuver her around with my belly in the way and not to mention the sore nipples 😣 I’d like to start weaning because idk how it’s going to work when the new one gets here. She’s exclusively breast so I haven’t pumped since she was a newborn. Any advice would be appreciated! Thanks in advance 😊
