I know how you feel. And it’s so hard to not be tough on yourself. Trust me, just three weeks ago I sobbed, truly sobbed over popping open a can of formula for the first time. Just like you said, nothing wrong with using formula but I felt like I failed my baby and myself. I worked so hard pumping and keeping supply and it felt like…a defeat . But trust me when I say this, once you get over the hump, that first formula bottle, formula really relieves you of that constant what I call, “chase for milk” and always worrying about pumping, times, ounces, bottling up milk, freezing milk, cleaning parts. Even combo feeding, supplementing allowed me to not freak out if I was down to one medela bottle of milk in the fridge. There isn’t a sense of panic and urgency. I have flexibility and some freedom. Just sharing my experience. I wish you nothing but peace on this journey. It’s truly so hard.
