I'm really sorry you're already dealing with criticism over this issue.

TBH I have no idea what breast hypoplasia is, so I can't comment on what effect it may or may not have on a woman's ability to breastfeed. I can speak from the position of being a mum to two girls who both had severe gut issues, resulting in them both being formula fed. I too was judged and lectured. At the end of the day, my girls were a lot happier and healthier on formula than breast. I was a lot healthier mentally and emotionally once they were happier and healthier.

Nobody has the right to judge you for the decisions you make, or the paths that are forced on you through circumstance. Breastfed or formula fed, you have already proved yourself to be an incredibly caring mother by doing so much work looking into your options and what may eventuate once your baby is born.

I wish you lots of luck, whatever feeding path you and your baby end up on.
