This is a submission in our monthly contest. October’s theme is Determination. Enter your own here!

Days into my daughter’s life, I learned that breastfeeding did not, at all, feel good. Every latch felt like a thousand tiny needles stabbing my nipple in unison. After a few moments, the sharpness would fade, replaced by my blunt determination. Nursing was the only thing that made my daughter happy.

I had thought breastfeeding would be easy to figure out, that I could leapfrog the issues that plagued others. Perhaps, because I had no experience with newborns, my brain filled the void with the most optimistic scenario.

My optimism evaporated within a week. Life became a series of marathon nursing sessions interrupted by short periods of sleep. Ten, 12, 20 times a day (and night) the pain pierced and took my breath away. I called her my milk vampire. My nipples cracked and blistered and bled.

My mother flew in from Chicago to help out. She kept me company on the couch for hours a day, the two of us watching “Bones” while I nursed her granddaughter. Sitting in my nest of pillows, I practiced each nursing position I’d been taught. I latched and re-latched my daughter, hoping each time it would make the pain go away.

My sleep deprivation worsened. My mother broke her arm, and my husband lacked the emotional endurance to soothe our always-fussy baby. In those first couple of weeks, my newborn daughter and I spent 20 hours a day in physical contact.

I expected my husband to bear these burdens with me. He expected me to soldier on, no matter the pain or misery. After three weeks, he went back to work, leaving me alone with only one effective parenting tool: my breasts.

Late one night, my husband snored while my daughter nursed voraciously. Just two weeks into her life, I wanted to scream at the pain. Instead I wept. “This can’t be right,” I thought. “This is why people use formula.”

At my loneliest, weariest time, I felt desperate for relief. I figured the signs of breastfeeding failure would be clear: If my daughter lost more than 10 percent of her weight after birth, or if the doctor mandated it. Never once did I consider that I could be in pain and exhausted, yet not quite failing completely.

I hadn’t chosen to breastfeed, not exactly. I had expected to breastfeed, the way a middle class teenager expects to go to college and expects to get a good job afterward. Feeding your child is a biological imperative. Humans have been doing it by breast for millions of years. My body would automatically make milk in the first week after birth whether I wanted it to or not. I felt entitled to an easy breastfeeding experience. Pain infringed upon my birthright.

In the dark, I hunched over my daughter like a frenzied, cornered cat, searching for escape. I saw formula dangling in front of me as the “easy solution,” the ever-present back-up plan. If I failed at breastfeeding, I knew I was supposed to transition to formula and convince myself to be happy about it. Liberated women must never feel guilty about their choices.

But nursing was my daughter’s sole source of comfort. I refused to give it up.

I needed fuel for my resolve, and I chose rage. I let myself hate formula and the people who sell it, their oily ads and counterfeit generosity. I turned on the parenting industry at large. So many useless gadgets, wasted time, and squandered hope. I seethed over the injustices of motherhood and its overflow of impossible decisions. But most of all, I raged against the breastfeeding mothers who failed to tell me how hard this all was.

I raged until I had no anger left. When I was done, I wept for my own naiveté in thinking the world was fair and all problems had solutions.

I woke the next morning, and many mornings after, feeling battered. Would my situation ever improve? I didn’t know. I couldn’t imagine tomorrow, let alone next month. Every moment lasted forever. My pain felt eternal.

At six weeks, the pain disappeared. It was nothing I did, no grand revelation. Maybe my daughter learned how to suckle properly, or her mouth grew a little. I’ll never know.

Now I can think of 50 things I could have done differently. But when I look back, I can never see the moment where I should have known better. Every time I replay these events, I make the same decisions. It was all I knew. My breastfeeding experience was not a gold medal performance or an A+ on a final exam. In an alternate reality, I might have surrendered to formula.

In this reality, I’m still surrendering to the realization that sometimes success can feel an awful lot like failure.
