WEANING HELP DESPERATELY NEEDED!!!

She's 20 months old and just won't stop. She screams to nurse and now being home 24/7 doesn't give opportunities to be out and distracting. If I apply anything on me she just screams or doesn't care. I'm not in a place to handle the tantrums anymore. I'm normally okay nursing this long but literally hate the feeling of it any more, and yes it makes me feel guilty too, but I need her to stop. My husband lives elsewhere, military, so I don't have that resource. I do have a 16 & 14 yr old though. So not sure if I need to utilize them, but how. The primary nursing issue is she won't fall asleep unless nursing. Please no negative comments, just positive and helpful. When my husband came for a visit a whole back I actually thought if I could get pregnant maybe she'd wean herself, like one of my other kids did lol. But unfortunately, that is going to take her weaning before I can get pregnant 🤦🏼‍♀️🤷🏼‍♀️🤣 the irony lol
