The Exact Moment My Twin Girls Decided to Become Fully Mobile

I was halfway through a tepid mug of Yorkshire tea when I heard the distinct sound of a skull making soft, rhythmic contact with cheap Swedish MDF. It was Tuesday, approximately 10:14 AM, and Mia had finally discovered how to operate her limbs—only she’d somehow put herself in reverse. She was currently wedged underneath the television unit, looking at me with an expression of deep, big betrayal, while her twin sister Lily was on the opposite side of the rug, executing a flawless, predatory commando crawl directly toward the dog's water bowl.

If you've ever found yourself scrolling through Mumsnet in the pitch black of 3 AM searching for the exact timeline of when do babies actually figure out forward motion, you’ve probably stumbled into the dark web of parenting forums. You know the ones. The places where sleep-deprived people frantically type things like "my babi is eight months and just sits like a sack of potatoes" or "is my babie broken because she only rolls to the left." I was right there with you, convinced my children were going to be immobile until university, right up until the morning my living room became a two-front war zone.

The timeline is a complete work of fiction

I had read the books. Page 47 of the heavy, threatening manual I bought during my wife's third trimester suggested that I should expect crawling between seven and ten months. But our health visitor—a lovely, exhausted woman who always looked like she desperately needed a gin—sat on our sofa while the twins stared blankly at her and told me that the whole crawling timeline is wildly unpredictable.

She said the World Health Organisation pegs the median age at about eight-and-a-half months, but then she casually dropped a massive bomb on my anxiety: the American authorities literally deleted crawling from their official developmental milestone checklists entirely. Apparently, a massive chunk of completely fine infants just decide crawling is a mug's game and skip it altogether. They just roll around for a bit, maybe scoot on their bottoms, and then stand up and walk away like miniature, terrifying adults.

It turns out that trying to force a timeline on twins who are completely oblivious to the Gregorian calendar is a fast track to madness. You just have to wait for them to realise that the television remote is on the floor and they want to put it in their mouths.

Weird shapes they make before actually moving

Before the horrific Tuesday of the dog bowl incident, I had noticed them doing some strange gymnastics. Our GP warned us that babies need to build up a ridiculous amount of core strength before they can actually go anywhere, which mostly involves them doing things that look like failed yoga poses.

• The aggressive plank: Lily spent about two weeks just pushing up on her hands and toes, vibrating with intense rage, before collapsing face-first into the carpet.
• The broken Roomba: Mia preferred to lie on her stomach and pivot in slow, erratic circles, sweeping the floor with her cardigan like a highly inefficient cleaning appliance.
• The desperate rock: Getting up on all fours and violently rocking back and forth, looking like they're about to launch themselves into low earth orbit, but honestly going absolutely nowhere.

The misery of the reverse gear

But nothing prepares you for the reverse gear. I need to talk about the reverse gear because it consumed my life for an entire month. Mia figured out how to push with her arms long before she figured out what to do with her legs. The physical reality of this meant that every time she saw a toy she wanted, she would lock her eyes on it, push incredibly hard, and immediately slide backward, away from the thing she loved.

It was tragic. It was Greek theatre playing out on a beige rug. She would scream, push harder, slide further away, and eventually end up wedged under the sofa, covered in dust bunnies, furious at the laws of physics. I spent weeks just fishing my daughter out from under various pieces of furniture.

I read somewhere that this backward sliding is highly common because their arms are stronger than their legs at that age, which makes sense medically but doesn't help when you're trying to cook pasta and your child has accidentally reversed themselves into the hallway and is now shouting at a radiator.

Lily, meanwhile, tried a bear crawl once—walking on her hands and feet with straight elbows and knees—looked like a tiny, aggressive drunk person, and never did it again.

Luring them with things they're allowed to chew

To stop Mia from reversing into the skirting boards, our health visitor suggested I get down on the floor and physically lure her forward with something highly desirable. You're supposed to dump them on a reasonably clean rug without all the restrictive bouncy chairs and plastic containment units, waving a slightly damp toy just out of reach while hoping they eventually figure out how their knees work in unison.

We started using the Bunny Teething Rattle for this exact purpose, and it's genuinely the only reason Mia figured out how to go into drive. I don't know what it's about this specific crochet rabbit, but the absolute chokehold it has on my children is terrifying. The wooden ring is heavy enough that I could slide it across the hardwood floor just out of reach, and the little bell inside would jingle. Mia would lock onto that neutral beige bunny like a heat-seeking missile. It’s brilliant because it’s totally untreated wood, so when she finally did drag her body across the floor to get it, she could immediately gnaw on it without me worrying about whatever plastics she was ingesting.

We also tried luring them with the Llama Teether Silicone Soothing Gum Soother. Look, it's a perfectly fine object. It does exactly what it says it does, and Lily enjoyed chewing on the little heart cutout. But I'm going to be completely honest with you: silicone is a magnet for dog hair. If you've a golden retriever who sheds like it’s a competitive sport, rolling a silicone llama across the floor means by the time your baby reaches it, it looks like a small, colourful rodent. We keep the llama strictly in the high chair now.

If you're desperately looking for ways to bribe your own children into forward motion without compromising your living room aesthetic, you might want to casually browse our collection of teething accessories and wooden play gyms. They're, at the very least, not covered in dog hair.

The completely unfair advantage of hardwood floors

One thing nobody tells you is how much your flooring dictates their success. We have a rug in the living room and hardwood everywhere else. Lily figured out that if she wore her organic cotton sleepsuit, the hardwood floor turned her into a human hovercraft.

She developed this highly specific bottom scoot. She would sit dead upright, plant one foot, and just drag her bum across the slick floorboards at alarming speeds. It was less of a crawl and more of a seated sprint. I mentioned this to our doctor, half expecting a referral to a specialist, but he just laughed and said babies are inherently lazy and will use whatever method burns the least amount of calories to acquire a dropped digestive biscuit.

If you seriously want them to do the classic hands-and-knees crawl, they need friction. We had to take their trousers off entirely. Just two babies in nappies, giving their bare knees some traction on the rug. It completely ruined my attempts at styling them in cute autumn outfits, but at least Mia stopped reversing under the television.

The illusion of childproofing

The transition from "stationary potato" to "mobile threat" happens overnight. You think you've time. You think, oh, they're just rocking on their hands and knees, I'll install the stair gates this weekend.

Don't wait for the weekend. The morning Lily reached the dog bowl, I had to physically sprint across the room to stop her from drinking stagnant tap water. That afternoon, I found myself sweating profusely, bleeding from the knuckle, trying to drill safety anchors into the plasterboard to secure a bookshelf because Mia had suddenly realised she could pull herself up on the bottom shelf.

You have to get down on your hands and knees and look at your house from their terrifying vantage point. To a nine-month-old, a trailing lamp cord is a climbing rope, and an uncovered electrical socket is a fascinating puzzle box. I spent a small fortune on those little plastic outlet covers, only to realise the twins found them highly entertaining to try and pry out with their fingernails.

When our GP seriously wanted to see us

Amidst all this chaos, it’s hard to know what’s normal and what’s a medical red flag. You read too much online and convince yourself that a slight drag of the left leg means impending doom.

Our GP was incredibly reassuring, but she gave me one very specific thing to watch out for. She said she doesn't care if they crawl backward, sideways like a crab, or scoot on their bums. She doesn't even care if they don't move at all until ten or eleven months. But she said the one thing that requires a phone call is asymmetry. If they're heavily favouring one side of their body—dragging one leg completely dead behind them while the other does all the work, or only ever using the right arm to pull—that’s when doctors seriously want to take a look to rule out any physical or neurological issues.

Thankfully, both my girls were equally chaotic on both sides of their bodies. Symmetrical destruction.

The 2 AM Panic Search (FAQs)

Is it totally normal if my baby just refuses to do tummy time?
Yes, and I feel your pain. Both of mine screamed into the carpet like I was torturing them. Our health visitor told me you don't genuinely have to leave them flat on the floor for twenty minutes straight. Rolling them onto your chest while you lie on the sofa counts. Putting them over your knee counts. They just need to practice lifting their massive, heavy heads against gravity without you supporting their neck. Break it up into tiny, less miserable increments.

What if they skip the hands and knees thing entirely?
My niece literally never crawled. She sat there like a tiny queen demanding tributes until she was ten months old, and then one day she pulled herself up on a coffee table and just walked off. Our doctor told me that as long as they're coordinating both sides of their body in some way and trying to explore their environment, the exact style of locomotion doesn't really matter. The classic crawl is highly overrated anyway; it just ruins the knees of their trousers.

Should I put shoes on them to help them grip the floor?
Absolutely not. I made this mistake. Put tiny trainers on Lily thinking she'd get better traction, and she just ended up looking like a confused tiny person wearing concrete blocks. They need to feel the floor with their bare toes to figure out balance and weight distribution. Bare feet are best, or if your house is freezing like ours, socks with those rubber grip bits on the bottom. Normal socks on hardwood floors will turn your child into a curling stone.

How do I stop them from crawling toward dangerous things?
You don't. You can't. They have a sixth sense for danger. If you place a beautiful, expensive, organic wooden toy on the left, and a choking hazard on the right, they'll choose the hazard every single time. Your only option is to completely sanitize the environment from the knees down. Put the dog bowl on a raised stand. Hide the television cables in plastic trunking. Surrender to the fact that your living room is now a padded cell for the next twelve months.

Can their outfits genuinely stop them from moving?
One hundred percent. We had this adorable, thick corduroy dungaree set that we got as a gift. Put it on Mia, and she was basically immobilised in a fabric cast. She couldn't bend her knees to get under herself. If you want them to practice moving, put them in something with massive amounts of stretch, or just let them go rogue in a nappy for half an hour. Dignity goes out the window when mobility is on the line.
