To answer your question: From the original post, quoted immediately below. I think this is not just a nursing vs bottle feeding issue. I think it has more to do with how overwhelming parenthood can be, especially if you haven't been around newborns much in your life. I know I was around a ton of newborns and competent at holding them and changing diapers, but it was still overwhelming in so many ways when I had one of my own. I'm just offering a little compassion for the OP's friend - and a possible way for the OP to get out of this swirl of conversations focused on feeding.
I know she was very overwhelmed by the whole thing, she had a extremely rough couple of days with the newborn, she didn't trust herself to hold him/change him/felt incompetent,etc. Breastfeeding took a back seat and they introduced formula because the baby "cried at night."
