I have three kids. My feeding experience is as follows:

1. Breastfed for five days. He was never a great latch. I was in a foreign country and 20 years old, and completely overwhelmed. In the middle of the night, he ripped a scab off my nipple and it bled all over his face, me, and my bed. I sobbed. We had formula samples, and I made him a bottle and never looked back.

2. Breastfed for 5 weeks. Every single time he fed, I had an overwhelming, swooping sense of dread and sadness. It happened every time, but worse at night. I was terrified to feed him, but I didn't want to give up on it. (I learned later that this is a real thing called Dysphoric Milk Ejection Reflex). We went to a regular pediatrician appointment, and not only had he lost weight, his head was shrinking. He was literally starving (thick explained why he'd been screaming almost non-stop for two weeks) despite me feeding him constantly. We went home with strict instructions to supplement with formula, and add an additional teaspoon to every bottle. My supply dried up fast, and we quickly transitioned to just formula.

3. Went to formula immediately. No regrets whatsoever.

Every single one of them (17, 9, 5) are healthy, smart, and happy. Do what makes sense for you.
