The Brutal Truth About Finding the Right Baby Winter Overall

I was standing in the gravel driveway of my mom’s house on a freezing November morning, sweating through my own flannel shirt, while my oldest child—who was maybe eight months old at the time—screamed like I was dipping him in acid. The wind coming off the pasture was howling, I had an armful of packages from my Etsy shop that needed to get to the post office, and I was trying to shove his rigid, starfish-shaped body into a cheap, heavily insulated baby winter overall I’d bought on clearance.

He couldn't bend his knees. He couldn't lower his arms. I finally got him zipped up, only to realize I now had to figure out how to strap this giant, screaming marshmallow into his car seat. I look back at pictures of him from that first winter and I just cringe, because I thought I was doing the right thing by bundling him up to the point of immobility. I honestly believed that maximum puff equaled maximum warmth.

I’m just gonna be real with you: figuring out how to dress a baby for the cold when you live out in the country and actually have to leave your house is a massive learning curve. Between the three kids I’ve had in the last five years, I’ve made every mistake you can possibly make with finding a winter overall that actually works for a baby's reality.

The marshmallow myth and my pediatrician's reality check

My grandmother, bless her heart, was from the school of thought that a baby needs to wear every piece of clothing they own if the temperature drops below fifty degrees. So with my oldest, I’d put him in a thick cotton onesie, a heavy sweater, and then the thickest winter overall I could find.

But when I took him in for his winter checkup, my pediatrician, Dr. Evans, looked at my red-faced, sweating infant and introduced me to the "Plus One" rule. He said that if I’m comfortable standing outside in a long-sleeve shirt and a medium jacket, the baby really just needs exactly what I'm wearing, plus one additional layer. Something about how their little bodies don't control heat the same way ours do, or maybe it’s their surface area to body mass ratio—I don't know the exact medical math, but the point was that I was roasting my child alive.

He told me I needed a three-layer system. You start with a base layer that actually breathes, put a warm middle layer over that, and then your baby's winter overall is the final wind-breaking shield. It changed my whole life.

For that base layer, I eventually threw out all my cheap stuff and started using the Organic Baby Romper Long Sleeve Henley Winter Bodysuit from Kianao. Listen, when you're dealing with winter blowouts, you need a base layer that doesn't require a master's degree in engineering to get off. This romper has these three little buttons at the top that make the neck hole wide enough to pull down over their shoulders instead of up over their head when disaster strikes. It’s mostly organic cotton with a tiny bit of stretch, so it hugs their skin enough to keep the draft out without turning them into a sweaty mess underneath their snowsuit.

Why I'll absolutely fight you over zipper placement

I've zero patience for clothing designers who clearly don't have children of their own, and the biggest offense in the history of baby clothing is a winter overall with a single zipper that stops at the crotch.

I once spent twenty minutes trying to thread my middle child's chubby little thigh into a straight-leg winter suit while my toddler was actively dismantling my shipping supply station in the other room. The baby was crying, the dog was barking, and I was trying to fold his leg in half like a piece of origami just to get it past the hem. It was awful.

If you're shopping for a winter overall, you must find one with an asymmetric zipper. I’m talking about a zipper that starts at the neck and swoops all the way down the front of one leg, ending near the ankle. Better yet, find one with two zippers that go down both legs. When you've dual zippers, you lay the suit flat, lay the baby on top of it, tuck their limbs in, and zip it up around them like a sleeping bag. You don't have to bend their rigid little knees. You don't have to play tug-of-war with their ankles. It just zips over whatever chaos is happening.

That terrifying car seat rule

Remember how I said I was trying to strap my marshmallow-baby into his car seat? Yeah, Dr. Evans practically had a heart attack when I casually mentioned that to him.

Apparently, putting a baby in a car seat while they're wearing a thick winter overall is a massive hazard. The doctor explained that in a car wreck, all that fluffy insulation just flattens out under the force of the impact, leaving the harness straps dangerously loose so the baby could literally fly out of the seat. That conversation made my stomach physically hurt.

So now, the routine is annoying but necessary: you've to take the winter overall off, buckle the baby tightly into their normal clothes, and then just lay a heavy blanket securely over their lap and chest once they're strapped in.

I keep the Organic Cotton Baby Blanket with Polar Bear Print permanently in my truck for exactly this reason. It’s double-layered, so it’s got enough weight to it that it doesn't just fly off every time I open the door to the wind, but it’s breathable organic cotton so they don't wake up drenched in sweat when the truck heater finally kicks into overdrive. Plus, the smaller size is exactly right to tuck around the edges of the car seat without hanging down into the floorboard muck.

Cold hands and Grandma's terrible advice

My mom and grandma are always grabbing my babies' hands when we're outside and gasping, "Oh my Lord, his hands are like ice, he's freezing!"

I used to panic and run inside, but Dr. Evans told me that feeling a baby's hands or feet tells you absolutely nothing about their core temperature. To find out if your baby is genuinely cold, you've to stick your hand down the back of their shirt and feel the nape of their neck. If it's warm and dry, they're completely fine. If it feels like a damp sponge, they're overheating and you need to start shedding layers.

Now, you still want to protect their extremities from frostbite because that's a real thing, but don't buy baby gloves. Have you ever tried to put gloves on an infant? You will spend an hour trying to line up their tiny, curled-up fists into individual finger holes. It’s a joke. You need a winter overall that has built-in, fold-over cuffs at the wrists and ankles. Mittens are vastly superior to gloves anyway because the fingers share body heat when they're trapped together in one little pouch.

Let's talk about neck strings for a second

If you find an adorable baby winter suit that has drawstrings around the hood or the neck, throw it directly into the garbage can because it's a strangulation hazard and I don't care how cute the little pompoms on the ends are.

Sweating in the freezing cold

One of the weirdest things about winter babies is how much they sweat. We will be out checking the mail in thirty-degree weather, and I’ll pull my youngest out of her suit and her hair will be plastered to her forehead.

If you want to build a wardrobe that naturally breathes and seriously makes sense for the cold, you might want to look at a collection of sustainable organic baby clothes that don't rely on cheap synthetic fabrics.

I do have to confess something about layering, though. I bought the Baby Sweater Organic Cotton Turtleneck Long Sleeve thinking it would be the ultimate middle layer to put under a winter overall. Y'all, I love Kianao, but putting a turtleneck on a six-month-old who barely has a neck is like trying to put a sock on a wet noodle. The fabric is beautiful and soft, and the curved hem is precious, but we honestly only use it on dry indoor days when I've the mental fortitude to wrangle it over his giant head. It's absolutely not my go-to layer for quick outdoor trips when I’m already stressed out. Stick to henleys or snap-necks for the heavy layering days.

Before you brave the cold this year, just remember that less is usually more, zippers are your best friend, and if you're sweating, your baby probably is too. If you're looking for layers that won't make your kid break out in a heat rash, check out Kianao's organic essentials.
