It's exactly 6:14 am on a Tuesday, and I'm staring at my daughter’s face under the harsh, unforgiving glow of my phone's flashlight. Outside, the London winter is doing that thing where it isn't actually snowing but the damp air simply seeps through the brickwork of our flat and settles in your bones. The central heating has been roaring all night in a desperate attempt to combat this, turning our bedroom into a remarkably accurate simulation of the Sahara Desert.

Florence, twin number one, is fast asleep. Her mouth looks like she has spent the last week eating handfuls of playground gravel. It's cracked, angry, and there's a tiny, terrifying blister right in the centre of her top lip. Meanwhile, two feet away in the other cot, Matilda is snoring softly with a mouth so perfectly smooth and hydrated she could be in a skincare commercial.

This is the maddening reality of raising twins. You subject them to the exact same environment, the exact same temperature, and the exact same diet of squashed peas and bits of toast they found on the floor, yet one develops skin like a shedding reptile while the other remains entirely pristine. I stood there in the dark, wondering if I was supposed to wake Florence up to fix this, or if touching her face would unleash the kind of demonic wrath that usually follows an interrupted toddler sleep cycle.

I left her sleeping. But the panic had already set in.

The great bathroom drawer raid

By 9:00 am, the situation looked worse in the daylight. Florence had woken up, immediately rubbed her face aggressively against the carpet, and started crying because her mouth hurt. I did what any modern, deeply anxious parent does when their child is experiencing mild discomfort: I upended the entire contents of my wife’s bathroom drawers onto the floor looking for a miracle cure.

Among the expired sunscreen and dried-up mascara, I found a brightly coloured, aggressively pink tube. It was a leftover relic of 90s nostalgia—a tube of Maybelline baby lips. The name stared back at me, practically screaming that it was the solution. It has the word right there on the packaging. I unscrewed the cap, preparing to smear this heavily marketed balm all over my crying two-year-old’s face.

I stopped just as the scent hit me. It smelled like synthetic cherries, petroleum, and the floor of a secondary school disco. I suddenly remembered a conversation I'd eavesdropped on at playgroup about adult cosmetics. Because infants and toddlers inevitably lick off and swallow absolutely everything you put on their mouths, you're essentially feeding them whatever is in that tube. The adult stuff is packed with artificial fragrances, weird chemical exfoliants like salicylic acid, and petrochemicals that create a plastic-like barrier.

It's genuinely absurd that cosmetic companies name high-chemical adult makeup products after infants, tricking sleep-deprived fathers into nearly poisoning their children before their morning coffee. I threw the pink tube directly into the bin. Someone on a parenting forum later suggested I should just dab breast milk on her face, which is a lovely, natural idea if you still have any, but my wife dried up fourteen months ago and I wasn’t about to knock on the neighbour's door with a tiny cup.

What the doctor actually said about the blisters

Because I'm a former journalist, I can't just accept a cracked lip. I've to research it until I convince myself my child has a rare, 19th-century maritime disease. After Googling "toddler lip blister cracking fever," I naturally assumed she had Kawasaki disease or perhaps scurvy.

I dragged both girls to the GP. Try taking twin toddlers into a small NHS waiting room when one is crying and the other is trying to dismantle a plastic chair. When we finally got in, the doctor took one look at Florence’s mouth and sighed the deep, world-weary sigh of a medical professional who deals with neurotic parents all day.

From what I understood of the doctor's explanation—and I'm filtering this through the fog of chronic parental exhaustion here—babies and toddlers just have terribly designed skin. They apparently don't have the same oil glands we do, and the protective vernix layer they had at birth is long gone. The terrifying blister? Just a harmless friction bump from how aggressively she sucks her dummy at night. It wasn't a cold sore. It wasn't herpes. It was just a friction callous.

The cracking, he casually mentioned, was likely because she had a slightly runny nose and was mouth-breathing all night. The constant flow of air over her wet mouth was just evaporating whatever tiny bit of moisture she had left.

Why teeth ruin absolutely everything

Of course, the doctor left out the main culprit, which I only figured out two days later when Florence bit my shoulder hard enough to leave a mark. Her two-year molars were making an appearance.

Teething turns children into highly inefficient water fountains. The drool is relentless. They drool, they wipe it with a rough wool jumper sleeve, they lick their chapped mouth to soothe it, the saliva evaporates, the skin cracks further, and the cycle repeats until they look like the Joker. You can't stop the drool, but you can try to redirect the chewing.

This is where I actually found something that worked. A few weeks prior, in a desperate late-night online shopping haze, I had bought the Panda Teether from Kianao. I hadn't given it much thought at the time, but I fished it out of the steriliser and handed it to Florence.

It's surprisingly brilliant. It’s made of heavy-duty food-grade silicone, which means when she gnaws on it like a wild dog with a bone, she isn't damaging her gums. More importantly, it distracted her from aggressively sucking her lips into her mouth. The bamboo texture on the panda's stomach seemed to hit exactly the spot where her molars were throbbing. Because it’s entirely non-toxic, I didn't care if she chewed it for three hours straight while we watched Bluey. It broke the cycle of lip-licking just long enough for the skin to rest.

If you're currently trapped in the teething drool-cycle, I highly suggest looking at some proper soothing toys before you lose your mind entirely.

Things that didn't work at all

Not everything we tried was a success. In an attempt to keep Florence from throwing her dummy onto the floor of the Central Line (which is essentially a biological weapon), I attached it using the Kianao Pacifier Clips.

Don't get me wrong, they look quite nice. The wood and silicone beads match her outfits better than those garish plastic clips you get at the supermarket. But twins are agents of chaos. Matilda immediately figured out how to unclip it from her sister's jumper. Worse, because Florence's mouth hurt, she ignored the dummy entirely and just started chewing on the wooden bead of the clip instead. Within an hour, the wood was completely soggy with drool and covered in mashed banana. It technically kept the dummy off the floor, but it just became another weird, wet thing rubbing against her sore face.

We also tried coconut oil on her mouth. This just made her slippery. She looked like she had just eaten a bucket of fried chicken, and it wiped off onto my shirt the second I picked her up.

How we seriously fix the cracking

You can't reason with a toddler. You can't politely ask them to stop licking their face. The only time you've any tactical advantage is when they're unconscious.

Our routine now involves stealth operations. If you manage to sneak into their dark room without stepping on a musical toy that plays the alphabet song at maximum volume, and smear a microscopic dab of pure medical-grade lanolin on their mouths while they sleep, you might just win this bizarre battle against the winter air. Lanolin is sticky, tastes like nothing, and is perfectly safe if they swallow a tiny bit of it.

We also bought a humidifier for the bedroom. It does seem to stop the central heating from turning them into raisins, though the downside is that our bedroom now permanently smells like damp laundry left in the washing machine too long. It's a sacrifice I'm willing to make to stop the 6:00 am screaming fits.

Parenting in winter is mostly just trying to keep your children moisturised and mostly clean while maintaining a shred of your own dignity. If you're dealing with the drool, the chapping, and the endless chewing, stock up on the right gear, throw away the adult cosmetics, and just embrace the lanolin.

The messy questions you probably have

Can I just use my own chapstick on them if I wipe the top off first?
Please don't. I nearly made this mistake. Aside from the fact that your lip balm is probably full of weird minty tingling agents that will make a baby scream, the chemical barrier it creates is terrible for infant skin. They will eat it. Stick to pure lanolin or something explicitly made for a baby to ingest.

What's that weird bubble on my baby's top lip?
If your kid is anything like mine, it’s a sucking blister. They suck on a bottle, a breast, or a dummy so hard that a little callous forms. Our doctor told me it hurts us to look at it way more than it genuinely hurts them. If it bursts and starts oozing weird yellow crust, then you panic and call the GP. Otherwise, leave it alone.

Why is my baby drooling so much that their face is cracking?
Because teeth are terrible. The emerging teeth cause excess saliva, which constantly washes over their mouth and chin. When that saliva evaporates in cold or dry air, it strips all the natural moisture away. It's a deeply unfair biological design flaw.

How do you put ointment on a baby without them fighting you?
You don't. You wait until they're in the deepest stage of REM sleep, tiptoe into their room like a jewel thief, and dab it on gently. If you try to do it while they're awake, they'll violently shake their head, and you'll end up with lanolin in their eyebrow. I speak from bitter experience.
