It's really hard to get a suppy going when a baby isn't feeding. I was pumping every two hours because my baby couldn't latch. It's not selfish for a woman who doesn't want to breastfeed to also not want to be a slave to a pump. I am sure if they did they would just give that milk to their baby anyway. Not breastfeeding isn't generally about not wanting to give your baby breastmilk it's more about the time and sometimes pain you have.

Some people may not feel comfortable having other children besides their child drinking their breast milk.

there's actually been a study on donating breast milk and people need to be careful when the donate or buy it. there's bacteria that has been found in majority of donated/sold breast milk that shouldn't be consumed by anyone. and if they're to sell/donate their milk then they might as well keep bf too.

Some people just don't want to go through that's.Breastfeeding and pumping is tough.
