I kinda get where she is coming from on this, because I think she’s having a very similar experience to me with my 2nd. Although I am a strong advocate for “fed is best” and I would never judge others for how they feed their babies, I was really tough on myself when it came to formula. I really wanted to keep breastfeeding and giving formula felt like admitting defeat. It was really difficult to take that first step, because it also feels like the first step to NOT breastfeeding any longer. Speaking for myself, I wanted to exclusively breast feed and give my son expressed milk (so that my husband could give bottles) but then my son started preferring bottles and I couldn’t pump enough to satisfy him. Then sure enough, as soon as I supplemented with formula it was swiftly downhill and by 6 months my breastfeeding journey was over. I was really sad as I don’t plan to have anymore children and I feel like the choice to stop was kinda out of my hands and now I’ll never breastfeed a baby again.
Anyway, I’m sure this is super boring to most people, especially if you’ve never had a baby. But my point is I can understand what she is saying, although I agree it doesn’t come across very well (perhaps she explained poorly). I don’t think anyone will really understand unless they’ve experienced it.
