I need help 😩

I’m 9 weeks pregnant and my 16 month old still nurses. At first I was like no biggie there aren’t health risks to it she doesn’t need the nutrition from me because she also eats solid foods I’ll just go with it. I need her to stop ASAP 😩 my nipples are so so so sore from pregnancy and her latching feels like I’m actually going to die. Being pregnant with her was a lot easier I only had slight morning sickness and it was manageable this pregnancy I’m nauseous all day long everything I do I feel like I’m going to puke and her nursing makes me feel so much worse. I feel bad having to make her stop and cold turkey won’t work for her she legit cries for hours on end no exaggeration until she vomits and then cries some more. She’s like me she needs to see things to understand so I’m thinking if she sees that I’m dried up and there’s no more milk she will stop. Does anyone know of anything safe to take or do to make my supply dry up that’s safe while pregnant?

Thanks in advanced ☺️
