It was late May, the temperature had inexplicably hit 22 degrees in London, and I was staring at my twin daughters in their double pram like they were gremlins about to melt in the light. They were barely four months old, completely bald, and possessing the kind of translucent, almost blue-tinged British skin that looks like it might spontaneously combust if exposed to direct ultraviolet radiation.

I had spent the morning frantically Googling what to do, which is always a mistake when you're already teetering on the edge of a sleep-deprived breakdown. I was standing in the middle of Victoria Park, trying to manoeuvre a massive piece of muslin cloth over the pram to block the rays, completely unaware that I was about to commit one of the cardinal sins of modern parenting.

The terrifying under-six-month blackout period

Our GP, a painfully calm woman named Dr. Patel who always looks at me with a mixture of pity and mild amusement, had casually mentioned during their immunisation appointment that babies under six months shouldn't wear sun cream at all. She muttered something about their skin being essentially like highly permeable tissue paper that absorbs whatever you put on it straight into the bloodstream, which frankly sounded like a design flaw to me.

Since they also apparently couldn't sweat properly to keep stable their temperature yet, she made it sound like putting cream on them would cause them to overheat like tiny, furious radiators. So there I was in the park, trying to construct a makeshift tent over the pram to keep them in total darkness. That was right up until a woman walking her golden retriever casually informed me that draping a blanket over a pram creates a lethal greenhouse effect, trapping the heat inside and turning the bassinet into an oven within minutes.

I snatched the blanket off so fast I nearly tipped the whole contraption over.

This leaves you with very few options when you've infants who can't wear protective gloop and can't be covered by a blanket. You basically just have to accept that your new summer aesthetic involves scurrying from tree shadow to tree shadow like a vampire while dressing them in full-body, lightweight armour.

This was the exact period when the Organic Cotton Baby Bodysuit became my absolute favourite piece of clothing we owned, largely because it meant I didn't have to worry about the sun hitting their shoulders. It's properly breathable, so they didn't get heat rash (which looks terrifyingly similar to meningitis if you talk to WebMD at 3am), and the neck actually stretches enough to get over Florence's massive head without a fight. It was infinitely easier to just snap them into organic cotton than to try and calculate the trajectory of the sun every time we left the house.

That magical half-year threshold

Eventually, we survived the newborn phase and crossed the six-month mark, which meant we were legally allowed to purchase the protective paste. I marched into Boots feeling incredibly smug, only to be confronted by a wall of products that required a degree in biochemistry to understand.

Dr. Patel had given me a rather loose explanation of the difference between chemical and mineral formulas, most of which I forgot by the time I reached the car park. From what I gathered through my blurry understanding of the science, chemical ones apparently absorb the light and turn it into heat (which sounds like literal witchcraft and also bad for the coral reefs, if my daughters ever find themselves swimming in the Great Barrier Reef rather than the local lido), while mineral ones use zinc oxide to act like millions of tiny mirrors sitting on top of the skin.

So, we went with the mineral mirror-paste. It's thick. It's unyielding. It makes your child look like a Victorian ghost who has just emerged from a flour mill.

The books all say you should do a 48-hour patch test on the inside of their wrist to check for an allergic reaction, a piece of advice I remembered approximately four seconds after I had already slathered both girls from head to toe on a beach in Cornwall. Thankfully, the only reaction they had was big irritation at my existence.

The logistics of the thick white paste

Nobody warns you about the sheer physical stamina required to grease a feral toddler. The official guidance I read somewhere suggested using half a shot glass of lotion per child, which is a wildly unhelpful metric for someone whose shot glasses are currently gathering dust behind the steriliser. I just squeeze out a golf-ball-sized mound and hope for the best.

Matilda acts like the cream is made of acid. The moment she sees the tube, her body goes completely rigid, and she begins a high-pitched wail that makes passersby think an abduction is in progress. Florence, on the other hand, just tries to eat it.

To get the stuff onto Matilda's face without getting a thumb in my eye, I've had to resort to psychological warfare. I clip one of those Wood & Silicone Pacifier Clips to her collar, not because she needs a dummy, but because she gets immediately distracted by trying to aggressively chew on the wooden cookie charm. While she's focused on destroying the beechwood, I frantically swipe a mineral stick across her nose and cheeks. Sticks are infinitely better for the face, by the way, because if you use lotion, they'll inevitably rub their eyes with their sticky fists and then you've a screaming, temporarily blinded child on your hands.

As for the body, you just have to pin them down and accept that your own clothes will be permanently stained with white zinc handprints.

We did try one of those fancy aerosol spray formats once, thinking it would save time. But the small print inexplicably tells you to spray it into your own hands first and then rub it on the baby to avoid them inhaling the fumes, which completely defeats the entire mechanical purpose of the spray bottle.

Acceptance and tactical retreat

By mid-summer, I realised that engaging in the lotion wars every two hours was slowly eroding my will to live. It's so much easier to rely on physical barriers.

Our hallway now looks like the staging area for an arctic expedition, just with wide-brimmed hats that feature those big chin straps (without a strap, a hat is just a frisbee waiting to happen). If we're going to the park, we take the Universe Pattern Bamboo Blanket. It’s perfectly fine for throwing on the grass for them to sit on, though Florence is obsessed with trying to chew the bamboo hem. It's soft and does the job as a ground sheet, but I must reiterate my earlier trauma: never, ever drape it over the pram to block the sun. Just buy a clip-on parasol and save yourself the anxiety.

If you want to save your sanity this summer, I highly suggest browsing the organic baby clothes collection for long, breathable layers so you only have to fight the cream battle on their hands and faces.

The absolute worst advice from relatives

The thing that always sends my blood pressure skyrocketing is the unsolicited advice from older relatives who survived the 1980s and therefore think they're dermatological experts. Auntie Susan came round last week, looked at my heavily shielded, zinc-covered daughters, and announced that they looked "a bit peaky" and needed "a nice bit of sun for their Vitamin D."

I had to physically bite my tongue to stop myself from reciting the statistic my paediatrician had casually dropped on me: apparently, just one severe, blistering burn in childhood can double a person's risk of developing melanoma later in life. Their skin is incredibly thin, they've basically no melanin, and I'm not risking cellular damage just so my two-year-olds can sport a "healthy glow" for the family WhatsApp group. They can get their Vitamin D from those weird, oily drops I hide in their porridge.

Also, whilst I'm ranting, don't buy those two-in-one bottles that mix the protective cream with insect repellent; the logistics are a nightmare because you've to reapply the cream every two hours, which means you end up heavily overdosing your child in bug chemicals.

We're still finding white zinc smudges on the sofa cushions from last August. I've accepted that during the warmer months, my children will look like they're preparing for a mime performance, and my own hands will constantly smell of shea butter and mild panic.

Before you brave the blistering heat of the local playground, make sure your changing bag is fully stocked with the protective, breathable layers you'll inevitably need. Check out our organic baby clothes to build your summer defence strategy.

Questions I frantically searched on my phone at the beach

Do I really have to reapply this stuff every two hours?
Unfortunately, yes. And immediately after they get wet, which includes the paddling pool, the sea, or simply sweating profusely while having a tantrum because you won't let them eat a handful of sand. The mineral layer rubs off surprisingly fast when they're dragging themselves across a picnic rug.

How on earth do I wash mineral paste off a baby honestly?
With great difficulty and immense patience. Because it's designed to sit on the skin and be water-resistant, a quick splash in the bath does absolutely nothing. I usually have to use a warm, wet flannel and a decent amount of baby oil or a very gentle body wash, scrubbing just hard enough to remove the zinc without taking off the top layer of their epidermis.

Can I just put a tiny bit of cream on my 4-month-old's feet if they're in the sun?
My GP basically told me that if you're trapped in the desert with zero shade and your baby's skin is exposed, a tiny dab of mineral paste on a small area like the toes or the back of the hands is better than a medical-grade burn. But it’s an absolute last resort. Shade and cotton are your actual friends here.

Why does my baby look purple/grey after I put this on?
Because the active ingredients, zinc oxide and titanium dioxide, are literally white rocks ground into a powder. Unless you buy one of the fancy tinted ones (which will ruin all your clothes immediately), the thick white cast is just part of the aesthetic. Embrace the ghost baby look; at least you can easily see the spots you missed.
