My forehead is currently resting against the cold Victorian anaglypta wallpaper of our hallway, and I'm quietly pleading with a ten-month-old. She is holding her mustard-yellow knitted beanie in her left fist like a triumphant gladiator holding a severed head. We're already twenty minutes late for a music class that costs more per hour than my first car, and her twin sister has just discovered how to undo the Velcro on her own chin strap. I'm sweating through my jumper. The twins are laughing.
There's a specific kind of madness reserved for parents trying to put a baby hat on a child who has decided their skull must remain forever unburdened. It's a physical impossibility. A baby’s head is essentially a lubricated bowling ball, and their neck—if you can even find it beneath the layers of adorable, milk-scented double chins—offers absolutely no purchase for any kind of fastening mechanism. You tie the little strings, feeling like a Victorian nanny, only for the child to look slightly to the left, instantly displacing the fabric so it covers one eye, giving them the appearance of a tiny, furious pirate.
But we persist, don't we? Because if you dare walk down a British high street in November with a bare-headed infant, an elderly woman materializes from thin air to tell you your child is going to catch their death of cold. It’s like they've a radar for exposed scalps.
The hospital tea-cosy deception
The whole obsession starts the literal second they're born. In the hospital, within roughly thirty seconds of my daughters arriving into the world, a midwife had wrestled them into these tiny, striped knitted things that looked exactly like tea-cosies. I was terrified. I thought, right, this is the rule now. The head must be contained. The head is vulnerable.
They tell you in the hospital that infants can't control their own temperature, which is a terrifying bit of information to hand to someone who hasn't slept in three days and is currently weeping at a television advert for life insurance. We brought them home to our flat in London, which has the thermal efficiency of a cardboard box, and I basically refused to take their hats off. I kept readjusting these tiny cotton caps while they slept, convinced I was saving them from instant hypothermia.
Then Brenda arrived. Brenda was our NHS health visitor, a woman composed entirely of tweed and blunt authority. She took one look at my daughters dozing in their Moses baskets with their little hats on and immediately told me I was creating a massive hazard. Apparently, that old wives' tale about humans losing eighty percent of their body heat through their heads is utter rubbish, or at least a massive exaggeration based on some flawed military study from the fifties.
Brenda informed me, in tones that suggested I was an absolute idiot, that babies cool themselves down by releasing heat from their heads. If you block that heat escape route while they're sleeping indoors, their tiny internal thermostat basically shorts out. I vaguely understood that overheating is a massive risk factor for SIDS, so I immediately panicked, ripped the hats off their heads, and threw them across the room (page 47 of the parenting manual suggests remaining calm in these situations, which I found deeply unhelpful).
Ditching the indoor paranoia
Once you realize indoor hats are essentially tiny woolen death traps, you've to figure out how to actually keep them warm without suffocating them. We spent an absurd amount of time worrying about them freezing in our drafty living room before realizing we just needed better base layers.

I ended up developing a slightly weird devotion to the Organic Cotton Baby Bodysuit. It's brilliant mainly because I don't have to think about it. The fabric is highly breathable so they don't get that horrible sweaty rash in the creases of their neck, and it's stretchy enough that I can wrestle it over two flailing heads without causing a meltdown. We just completely abandoned the idea of indoor headwear and shoved them in these instead, layering a jumper on top if the heating was playing up. It completely removed the anxiety of constantly checking if their heads were sweating.
If you're currently stressing about your house being too cold, just feel the back of their neck or their chest to check their temperature rather than aggressively touching their icy little hands, and layer up their core instead of trapping the heat in their skull.
As for sizing headwear when you do actually need to go outside? Just buy the ones with the stretchy ribbed bit at the bottom, their heads grow at a terrifying, unpredictable rate anyway so precise measurements are a fool's errand.
The absolute indignity of summer headwear
If winter hats are a logistical nightmare, summer sun protection is an exercise in public humiliation. Because you can't slather a newborn in sunscreen, their only defense against the sun is shade and fabric. This means you've to buy them a legionnaire hat.
You know the ones. They have a massive peak at the front and a long flap at the back to protect the neck. They make every child look like an eccentric birdwatcher who has lost his binoculars. My girls despised them with a fiery passion.
During the heatwave last year, getting them to keep their UV hats on while in the pram required actual bribery. I bought the Panda Teether Silicone Chew Toy purely as a tactical distraction. It’s alright, to be honest. It’s just a bit of silicone shaped like a panda, but it gave their hands something to aggressively gnaw on instead of reaching up to rip their hats off. I’d shove the teether in their mouth, jam the legionnaire hat onto their head, and sprint to the shade of the park before they realized what had happened.
Of course, the minute we were safely back indoors, the hats were immediately discarded onto the floor. Which is fine, because indoor play is blessedly hat-free territory. We’d just dump them under their Rainbow Wooden Baby Gym in the living room and let them roll around in their natural, bare-headed state, batting at the wooden elephants while their body temperatures regulated themselves perfectly without my intervention.

The "one layer more" confusion
If you ever ask a baby sleep consultant on Instagram—which I suggest doing only if you enjoy feeling entirely inadequate—they'll tell you about the "one layer more" rule for outdoors. The idea is that an infant needs exactly one more layer of clothing than an adult would wear in the exact same weather.

This sounds perfectly reasonable until you realize adults are completely inconsistent. I run hot; I'm entirely comfortable in a t-shirt in mid-October. My wife runs cold; she wears a massive puffer jacket indoors if the thermostat drops below twenty degrees. So whose layers are we adding to? If we base it on me, the twins will freeze. If we base it on her, they'll spontaneously combust.
I eventually just guessed. If my breath plumed in the air, a winter beanie went on. But the golden rule I eventually figured out, mostly through trial and error and mopping up sweaty foreheads, is that the hat comes off the absolute second you transition back indoors.
Walking into a café? Hat off. Getting into a pre-warmed car? Hat off. Pushing the pram into the supermarket where the heating is blasting? Hat off. Yes, it wakes them up sometimes. Yes, wrestling a hat off a sleeping baby is like trying to defuse a bomb with chopsticks. But it’s significantly better than them overheating because they're stuck in a fleece-lined trapper hat next to the bakery aisle radiators.
Ready to abandon the indoor hat struggle and just let their little bald heads breathe? Stick to quality layers and save your sanity.
Desperate late-night queries about infant hats
Do babies seriously need to wear hats indoors?
Absolutely not, unless you're still sitting inside the hospital room in the first forty-eight hours of their life. Once you bring them home, assuming you don't live in an actual igloo, indoor hats are a terrible idea. They trap heat and stop your kid from regulating their temperature, which my health visitor aggressively informed me is a massive hazard. Just use decent layers instead.
How do I know if my kid is too cold without a hat?
Don't touch their hands or feet. Infant extremities are basically ice blocks by default because their circulation is terrible. Shove two fingers down the back of their onesie and feel the nape of their neck or their chest. If it feels warm and dry, they're completely fine. If it's sweaty, they're too hot. If it's cold, add a jumper, not a hat.
Can they sleep in a beanie if the room is drafty?
Never. Seriously, don't do it. A hat can easily slip down over their face in the dark and block their nose, or they can overheat wildly because they release excess body warmth through their scalp. If you're worried about drafts, get a well-fitted baby sleeping bag.
What's the best way to keep a sun hat on them?
There's no foolproof way, they'll fight you. But avoiding string ties (which are a strangulation risk anyway) and looking for soft Velcro straps under the chin helps. I usually just give them a teething toy to occupy their hands while I quickly fasten it, then point out a dog or a bus to distract them from the fact that they're wearing it.
Should I put a hat on them in the car?
Only if the car has been sitting in freezing weather and hasn't warmed up yet. Once the heater kicks in, you really need to reach back and pull it off them. Car seats are essentially highly insulated plastic buckets that trap body heat against their backs, so adding a winter hat to the mix is a fast track to a screaming, overheated child.
