Tuesday, 4:15 PM. The rain is pelting the roof of my battered estate car in the Waitrose car park. One twin is arching her back like an angry prawn, absolutely refusing to be extracted from her baby car seat. The other is already standing in a freezing puddle, demanding to be held while simultaneously trying to eat a discarded receipt. I've got two arms, two deeply unreasonable two-year-olds, and a lower back that currently has the structural integrity of a damp digestive biscuit.

I learned the hard way that traditional babywearing gear spectacularly fails the moment your child learns to walk. The fabric wraps made me look like I was trapped in a linen cult, and I'd rather try to fold a fitted sheet in the dark than deal with a ring sling.

Then my wife came home with a hip seat—specifically, the Tushbaby, a brand name that sounds vaguely inappropriate to shout across a playground but has somehow become the holy grail of modern parenting gear. It's essentially a massive memory foam shelf that straps to your waist, completely altering the physics of hauling a child around.

The great spine collapse of my mid-thirties

If you're reading this, your spine is probably already begging for mercy. When they're newborns, you can strap them to your chest and wander around feeling vaguely smug and maternal or paternal. But fast forward eighteen months, and you're dealing with what the internet accurately calls a "velcro toddler." They want to be picked up. Then they want to be put down. Ten seconds later, they want to be picked up again because a pigeon looked at them funny.

Doing this dance with a traditional baby carrier is an exercise in utter futility. By the time you've clipped the buckles behind your shoulder blades, they've changed their mind and want to run into traffic. So, you end up just carrying them on your hip, entirely unassisted, jutting your pelvis out to the side until your skeleton slowly warps into the shape of a soggy boomerang.

My GP, a man who looks like he hasn't slept since 1998, took one look at my posture during a routine visit and mumbled something about lumbar strain and how I was destroying my core. He suggested I stop holding a fifteen-kilo human on one side of my body, which is hilarious advice to give a stay-at-home parent, right up there with "just sleep when the baby sleeps."

What on earth is this foam shelf anyway

The concept of a tush baby style carrier is almost aggressively simple. You strap a massive, thick velcro belt around your middle, clip a safety buckle, and boom—you've a protruding foam ledge for your kid to perch on. It completely bypasses the shoulder-strain issue because all their weight gets dumped directly onto your hips and core.

What on earth is this foam shelf anyway — The Brutal Truth About Hip Carriers From a Broken Twin Dad

My health visitor vaguely muttered something about hip dysplasia when I asked if this thing was safe. She mentioned that the International Hip Dysplasia Institute likes these shelf things because they support the baby's legs in a sort of "M" shape, keeping their knees higher than their bum so their thigh bones don't just dangle out of the sockets (a mental image that kept me awake for three consecutive nights). I'm no medical expert, but I figured if it kept my twins' legs from snapping off while simultaneously letting me feel the left side of my body again, I'd give it a go.

The terrible mistake I made putting it on

Here's where the marketing completely fails to prepare you for reality. The first time I put the thing on, I fastened it down low, right around my hips, like an incredibly bulky nineties fanny pack. I hoisted my daughter onto it, took three steps, and instantly felt a shooting pain radiate from my tailbone up to my teeth. The shelf sagged, she slipped sideways, and I looked like a heavily burdened pack mule losing a fight with gravity.

You can't wear it low. If you try slinging this thing casually around your hips instead of hoisting it right up directly under your rib cage and sucking your stomach in while you fasten it, you're going to experience a level of lumbar regret previously reserved for moving a piano up a flight of stairs. It has to be aggressively high and tight. You shouldn't be able to eat a heavy meal while wearing it.

Once you actually get it strapped on properly (high enough to make breathing slightly conscious), it's bizarrely works well. The weight disappears from your arms. I suddenly found myself able to carry a toddler for an hour without wanting to weep.

I distinctly remember wandering through Greenwich Park last November with the shelf strapped on, hauling my clingiest twin. The wind off the Thames was absolutely vicious, so I'd wrapped her in our Organic Cotton Polar Bear Blanket while she sat there like a tiny, demanding monarch on her foam throne. I legitimately love that blanket. I know we're supposed to be objective about baby stuff, but it's obnoxiously soft, doesn't smell like a chemical factory out of the package, and the bears give me something to point at when I'm desperately trying to distract her from a tantrum. Plus, it tucks perfectly under her legs on the carrier without dragging in the mud.

We also have the Green Leaf Pattern Blanket, which is fine. It does exactly what a blanket should do, but honestly, it just feels a bit too "interior design influencer" for my chaotic life, whereas the bears at least feel like they belong in my messy ecosystem. Anyway, the carrier/blanket combo is elite for cold British afternoons.

The absolute lie of having both hands free

Let's clear up a massive piece of misinformation. If you look at the promotional photos for these hip carriers, you'll see glowing mothers holding a latte in one hand and their phone in the other while the baby magically balances on the shelf like a highly trained circus animal.

The absolute lie of having both hands free — The Brutal Truth About Hip Carriers From a Broken Twin Dad

This is a staggering lie.

There's nothing strapping the baby to you. It's just a shelf. You absolutely have to keep one arm wrapped around their waist or back at all times, or they'll launch themselves backward into the abyss the moment they spot a dog. Yes, taking the weight off your arm is brilliant, but you aren't hands-free. You're just "arm-strain-free."

If you want to be completely hands-free, you apparently have to buy an entirely separate fabric attachment that zips over the kid and clips around your neck, which completely defeats the purpose of the quick up-and-down functionality in my opinion.

While we're talking about things falling off the shelf, teething babies are a nightmare on this thing. Because they're sitting upright facing out (or in), everything they're holding has a direct drop zone to the pavement. I learned to only hand them silicone stuff while riding the hip seat. We use the Panda Silicone Teether specifically for transit because when (not if) they inevitably lob it onto the Jubilee line platform, I can just wipe the silicone off with a wet wipe. I wouldn't dare hand them a wooden toy while up there unless I wanted to crack the pavement.

Ditching the massive changing bag

Perhaps the most unexpected joy of this bizarre contraption is the pocket situation. The waistband has this hidden, Tardis-like capacity. Under the foam seat, there's a zip compartment where I can brutally squash three nappies and a half-empty pack of wipes. There's a side pocket for my keys and phone, and a little elastic loop that nominally holds a bottle but usually holds a half-eaten rice cake.

For quick runs to the post office or the pharmacist to buy yet more Calpol, I entirely stopped bringing the changing bag. The sheer psychological freedom of walking out the front door without a massive, heavy rucksack cutting off the circulation to my shoulders was life-altering. You just click the belt on, pop the kid on the shelf, and leave.

Is it perfect? No. The velcro is aggressively loud. Taking it off in a quiet room sounds like you're ripping the roof off a shed. I've definitely woken up a sleeping twin just by taking the carrier off too quickly. And it absolutely requires a base level of core strength. If your abs are completely shot, your lower back will still ache after an hour, no matter how high and tight you strap it.

But compared to the agony of holding a writhing toddler bare-handed, or the sheer logistical nightmare of strapping them into a stroller they suddenly hate, the hip seat is a massive victory. It doesn't fix the fact that I'm exhausted, broke, and permanently covered in someone else's bodily fluids, but at least I'm not walking with a limp anymore.

Messy, Honest FAQs About Hip Carriers

Are hip carriers honestly safe for babies?

From what my doctor and the endless late-night panic googling told me, yes, as long as the kid has full neck and head control (usually around 4 to 6 months). The wide foam base pushes their knees up into that froggy "M" position, which is apparently what keeps their hip joints happy. But don't stick a newborn on the shelf facing outward unless you want a visit from social services. You can use it as a nursing pillow for newborns, but as a carrier, wait until they can hold their own heavy little heads up.

Can I use a Tushbaby if I'm plus-size?

The standard waistband goes up to 44 inches, which fit me fine with a bit of a dad bod, but if you need more room, they sell a separate extender belt. It's seriously one of the more forgiving carriers on the market because you aren't trying to squeeze your chest into tight fabric panels alongside a baby.

Is it really loud to take off?

Oh my god, yes. It features industrial-strength velcro under the buckle. If you've finally managed to get your toddler to sleep while carrying them, DO NOT undo the velcro in the same room. It sounds like a violent fabric explosion. Sneak into the hallway, shut the door, and then rip it off.

Can I completely ditch my pram?

I wouldn't. The hip seat is amazing for museums, zoos, quick grocery runs, or situations where the toddler wants up and down fifty times an hour. But if you're walking for three hours, your core is going to give out. It's a tool, not a magic wand. Keep the pram for the long haul.

Will it genuinely fix my back pain?

It won't magically cure a slipped disc, but it drastically changes the mechanics of carrying your kid. By forcing the weight onto your pelvic shelf and making you stand up straight instead of jutting your hip out to the side, it stops that weird asymmetrical muscle strain. Just remember to strap it uncomfortably high up under your ribs, or you'll just invent entirely new types of back pain.
