Nursing while pregnant

Marietta

I am a mother of two girls. My oldest is 8 and stoped nursing on her own at 6 months. My youngest is 18 months and is still nursing. I am currently 11w 4days pregnant with twins. My nipples have reached the stage in pregnancy where they are very sensitive and nursing is becoming uncomfortable for me. I do not want to cut her off but feel it’s best for my sanity. The problem is she is not responding well to my trying to wean her. Throwing tantrums and hitting me. Just making me feel like I’m making the wrong decision. She is not taking well to cows milk or coconut milk. I’m also co sleeping with her still. What steps should I take to make this easier for her? I fear if I continue to nurse till baby’s are born she won’t share it will create a huge problem for all kids.
