I read recently about how thousands of cattle in Kansas died due to heat stress. They didn’t die from one day of hot temperatures, necessarily. But the persistent extreme heat and humidity that hit many parts of the country–particularly this one region in Kansas–wreaked havoc on herds.

Cattle can usually adapt to the summer heat. Studies show they’re resilient animals, but as one article told me, when there are multiple stressors involved, the animal struggles to cope. Not only that, but cattle need the lower nighttime temperatures to bring their internal temperature down. When nighttime temps are too high, they don’t release enough of their internal heat, and it continues to build and build and build, causing major problems when that cycle persists. Eventually, they can’t carry the cumulative heat load built up in their bodies. “Right now, if we don’t have night-time cooling hours, the animal won’t be starting each day at thermo-neutral, so they’re more at risk on the second or third day,” one veterinarian said.

Okay, let’s acknowledge the elephant (cow?) in the room. Yes, I’m about to compare us to cattle. My metaphor obviously breaks down pretty quickly, but bear with me…

“I’m pregnant,” I tell my husband, matter-of-factly. By the fourth kid, the announcements get a little less creative and a little more impromptu. We stand in the middle of the kitchen, dirty dishes piled high in the sink and a stack of unopened mail next to us. I can see him start to lean on the corner of the counter, trying to gain his composure.

His eyes grow wide. “No… you’re not. Seriously?”

We’re planners and preparers, prone to meticulously calculate my cycle and predict when pregnancy can and cannot happen. This one takes us both by surprise.

I show him the positive pregnancy test, revealing those two pink lines like a confession. I always wanted one more; he was content with three. I’m unsure how to interpret his stunned silence.

“Are you mad?” I ask, trying not to cry.

“I just need to lay down for a few minutes,” I tell my husband, Colson, as soon as he walks in the door from work. It’s been a day, and I can feel the exhaustion in every muscle. The head cold making its way through our home seems to have camped out with me longer than everyone else. I also feel like I’ve been on the verge of throwing up pretty much all day long.

I collapse into bed, basking in the quietness of my room. Not three minutes later, I hear screaming.

You know the kind—it’s more than a tantrum and more than a bump or bruise. I should probably go see what’s going on.

I throw off my comforter and stomp down the stairs, a bit too annoyed at the audacity of my child to interrupt my precious alone time with her yelling.

“What’s going on?” I ask Colson, with more than a hint of frustration.

“Izzy fell. I think it’s bad.”
