My mom thinks breastfeeding is gross... ):

I’m a FTM, 18, and living at home until I am more stable financially. Every time I bring up how I want to breastfeed to my mom, we get into a huge argument. She thinks it is “absolutely disgusting” She doesn’t want me to do breastfeed in her house because she thinks my little brother & stepdad will sexualize it. She also wants me to be able to have a cigarette or a drink when I am stressed out. She will not support me at all and it makes me extremely sad because I know all the benefits breastfeeding has for my daughter and I. I’m due tomorrow and don’t know what to do/: Do I not breastfeed because she won’t allow it in her house or do I say F it and do it anyways?
