It is interesting to read through these comments and see the varying experiences from everyone. I think that that once again shows that based on your experiences and circumstances you have to make the decisions that are best for your family and quite possibly recieve backlash either way.
I think this article is meant to defend the mothers who have chose to FF for whatever reason (honestly they don't need a reason or to justify themselves but I understand why they feel the need to defend themselves since people can be quite judgey either way). While if you are able to stay home with your baby, breastfeeding can be a much cheaper alternative, thats not really the case for some moms who have to pump due to work, latch issues, supply issues, etc, it can become quite expensive at that point. I think the purpose of the article is not to shame moms that chose to BF but to help people have empathy for both sides and not just go off shouting about how BF is free and readily available becuase thats not neccesarily true in all cases. Though I will concede that it possibly does so a little garishly.
My milk never came in much, I spent pretty much my whole maternity leave pumping and trying to get my son to latch before my milk just completely dried up at 4 months even after going to the doctors and trying all the supplements, pumping regimens and etc. that they suggested. I dont know why but I just couldn't produce enough milk. My hospital in the US also refused to let us try formula while we were there even though my son had orange crystallized urine from being dehydrated and instead insisted I try to breastfeed him every hour since he was dehydrated. We had to be there longer than normal due to a complicated birth/labor that ended in an emergency c-section. And I saw a lactation consultant multiple times a day every day that I was there. (Which cost ALOT of money since my insurance only covered one meeting) After the first two days of being home sobbing that he wasn't getting enough milk, my mom gave me a hug and said it was ok to supplement or just give formula 100% if thats what I wanted to do. So from that point on I would breastfeed on both sides and then give him a bottle. And then pump after giving him a bottle to try to get my milk to come in more usually getting about an ounce in total. My whole life surrounded around feeding him as much breastmilk as I could. Then right after he turned 4 months I had a day where I fed him on both sides, fed him 3 oz of formula becuase I was out of my pumped milk and then pumped both sides at the same time for an hour and only got 1/4 an ounce in total from both sides. So I called my husband cried my eyes out and decided to give up. It was so hard to juggle working from home, a baby, and pumping constantly to only get 1/4 an ounce. I was so defeated and felt like I didn't deserve to be a mother since I failed so miserably at BF. (My own harsh thoughts toward myself not what others said... also not true.) So from that point forward we gave formula and my son is super healthy, hits his growth curve perfectly, has hit every developmental milestone, super happy, well adjusted baby who has a very strong bond with me and my husband. (Not to say those things can't also happen with BF if it works out for you.)
The point is that BF isn't always an option or doable for all moms. Formula is needed and the shortage is having real and devastating impacts on some families and BF isn't an option for those families for whatever reason.
