Here is the answer up front, because you are probably reading this at 11pm surrounded by camping kit you are not sure about: a baby sleeps in their own travel cot, inside the tent's bedroom compartment, on the cot's own firm, flat mattress, in a correctly sized baby sleeping bag. Not in your sleeping bag, not on your airbed, and not tucked in beside you under a shared duvet.
Everything else in this guide is the practical detail that makes that answer work in a field: how to fit a cot into a tent that suddenly feels smaller than the brochure suggested, how to blunt a 4:45am summer sunrise, where naps happen when there is no nursery, what pack-down morning really looks like, and what to do when a full-size travel cot honestly will not fit.
Their own cot, their own surface: the short answer
Under canvas, a baby sleeps exactly where they sleep at home: on their own separate, flat, firm surface, and for most families that means a travel cot. It goes up inside the tent's bedroom pod, baby goes into it in a vest, sleepsuit and baby sleeping bag, and the familiar routine carries on with a greener view through the door.
It is worth being clear about what the answer is not. A baby does not sleep in your sleeping bag, on your airbed, in the middle of a zipped-together double bag, or loose on a camping mat under a shared blanket. Airbeds are too soft and too unstable, adult bedding is an overheating and suffocation risk, and none of it meets the Lullaby Trust's safer-sleep principles. The tent is new; the rules are not.
If this is your first trip, our full guide to camping with a baby covers kit, site choice and the wider logistics. This one stays on the single question that keeps new parents up at night, which is where the baby actually goes when the sun sets.
Fitting a travel cot into a tent
Set up, most travel cots occupy roughly 120cm by 65cm of floor, plus a little standing room around them for the 2am lean-in. In tent-berth arithmetic, that is about one adult's worth of space, sometimes a touch more, because cots have rigid corners and tents have sloping walls. The old rule holds: choose a tent rated for at least two more people than you actually are. Two adults and a baby are comfortable in a five or six berth tent, and cramped in a four.
Bedroom pods matter more than the overall berth number. Many family tents divide the sleeping area with a zip-out divider, and a cot usually swallows one full pod or half of a large one. Check the pod's actual floor dimensions rather than the rating, and remember the walls lean inwards: a pod that is 140cm wide at ground level can be much narrower at cot-rail height.
Position the cot in the middle of the pod, away from the tent wall where condensation drips and cold transfers through, and clear of the door you will be unzipping all night. Pitch on the flattest ground you can find; a slope you would never notice on foot is glaring in a cot, so it is worth asking for a flat pitch when you book. Somewhere like The Real Campsite at Park Farm near Faringdon, with nine enormous pitches and a private loo and water tap on each, makes the whole night shift easier, including the 3am nappy.
Finally, do a full practice run at home, cot inside tent, before you leave. Every travel cot has a locking mechanism apparently designed by someone who has never held a crying baby.
Safer sleep does not change under canvas
Everything the Lullaby Trust says about home applies in a field. Baby sleeps on their back, on a flat, firm, separate surface, with a completely clear cot: no pillows, no duvets, no cot bumpers and no loose blankets for babies under one. Warmth comes from layers, a vest and sleepsuit under a baby sleeping bag with a tog to suit the forecast, never from piling things on top.
Check temperature at the chest or the back of the neck, not the hands; cold hands are normal and tell you very little. Keep hats for outdoors and daytime, never for sleep, because babies shed excess heat through their heads. For tog choices, layering and the full cold-night playbook, see our guide to keeping a baby warm when camping.
One rule deserves its own plain sentence. Never bring a lit or smouldering BBQ, a gas stove or any fuel-burning heater inside or near a closed tent or awning, whether to cook or to warm it. Carbon monoxide kills quickly and silently in enclosed spaces, and a cooling BBQ keeps producing it for hours. If the forecast is cold enough to tempt you, the answer is more layers or a later trip, never a flame.
Beating the 4:45am summer sunrise
A tent is essentially a large lampshade, and midsummer dawn in southern England arrives before 5am. You cannot fully fix this, but you can blunt it. Start with the tent itself: many family tents now come with darkened bedroom fabric, and if you are buying anyway it is the single most useful feature for parents. Then pitch thoughtfully, with the bedroom facing away from the sunrise and, if you can, in the morning shadow of a hedge or treeline.
For the cot, a purpose-made breathable blackout cover designed for travel cots can genuinely buy you an hour. The word breathable is doing the safety work in that sentence: never improvise with a blanket, towel or coat draped over the cot, which traps heat and restricts airflow. If you would rather darken the room than the cot, clip or peg blackout material to the inside of the bedroom pod instead.
Be honest with yourselves about the ceiling here. You are negotiating with the sun and a dawn chorus, and the realistic win is 6am rather than 4:45. A consistent bedtime routine under canvas helps more than any gadget, because a baby who settles well resettles better too.
Naps without a nursery
Daytime sleep is where camping differs most from home, because there is no dark, quiet room to retreat to, and a tent in July sunshine quickly becomes far too hot for a sleeping baby. Do not put a baby down for a daytime nap in a hot tent; find shade and moving air instead.
The two reliable tools are the sling and the buggy. A sling walk around the site or the nearest footpath sends most babies off within minutes, with baby held high and close, face always visible. A buggy or carrycot parked in the shade of the awning, brakes on and an adult always nearby, covers the longer lunchtime nap; use a clip-on sunshade rather than a muslin or blanket draped over the hood, which turns a buggy into a greenhouse. Babies under six months should be kept out of direct sun altogether.
Site choice quietly matters here. A calm, orderly park suits nap schedules far better than a festival-adjacent field, and Mayfield Park near Cirencester is exactly that sort of place: quiet, spotless, open all year and popular with families who like early nights. Expect naps to run shorter and stranger than at home regardless; camping days are stimulating, and most babies make up the difference at night or in the car home.
Pack-down morning, honestly
The travel cot is the last big thing you can drop, because baby was asleep in it an hour ago, and it will be damp with dew or condensation even after a dry night. The routine that works: feed baby, hand baby and breakfast to one adult, and have the other strip and fold the cot early so the fabric gets some drying time draped over the car while the tent comes down.
Two small habits save you later. Stand the cot on a folded blanket or spare groundsheet all weekend so the base stays clean, and if it does travel home damp, open it up again within a day, because a travel cot that goes into the loft wet comes out speckled with mould. Allow roughly twice the pack-down time you managed before children, and count it a good morning if only one of you cries.
When a travel cot genuinely will not fit
Some tents are simply too small and some cars are too full. For young babies who cannot yet roll or push up, a pop-up travel bassinet gives a flat, firm, separate surface in a fraction of the space; check the age and weight limits, and retire it the moment baby starts rolling.
The carrycot from your travel system is the other honest option for small babies. It is flat and firm, and some manufacturers approve occasional overnight use, so check your model's instructions rather than guessing. Keep the same clear-surface rules inside it as you would in a cot: nothing loose, baby on their back.
For toddlers from around 18 months to two, the problem largely dissolves: a self-inflating mat on the floor of their own pod, with a toddler sleeping bag, works well, and there is nowhere to fall. What never becomes an option at any tent size is a baby sharing an adult airbed, sleeping bag or duvet. If the choice is genuinely between that and not going, the answer is a bigger secondhand tent, a one-night trial close to home, or waiting a season. Fields, happily, are patient.
Questions parents ask
Where does a baby sleep in a tent?
In their own travel cot in the tent's bedroom compartment, on the cot's firm, flat mattress, dressed in layers and a correctly sized baby sleeping bag. The same Lullaby Trust safer-sleep rules apply as at home: baby on their back, on a clear, separate surface, never sharing an adult airbed, sleeping bag or duvet.
What size tent do I need to fit a travel cot?
Most travel cots measure roughly 120cm by 65cm once set up, about the floor space sold as one adult berth. As a rule of thumb, choose a tent rated for at least two people more than you actually are, so a five or six berth tent for two adults and a baby, and check the bedroom pod's real dimensions before buying.
Is it safe for a baby to sleep in a tent overnight?
Yes, provided you follow the same safer-sleep principles as at home: own flat, firm surface, completely clear cot, a baby sleeping bag rather than blankets, and sensible layers for the temperature, checked at the chest rather than the hands. Never bring a lit or smouldering BBQ, stove or fuel-burning heater inside or near the tent to warm it: carbon monoxide kills.
Can my baby sleep in a pram carrycot overnight while camping?
Some lie-flat carrycots are approved by their manufacturers for occasional overnight use, so check your model's instructions before relying on it. The Lullaby Trust's principles still apply: a firm, flat, clear surface with baby on their back. A carrycot can be a reasonable stopgap for a small baby in a small tent, but a travel cot is the better long-term answer.
Can my baby share an airbed or sleeping bag with me in the tent?
No. Airbeds are too soft and unstable for babies, and adult sleeping bags and duvets carry a real risk of overheating and covering baby's face. A baby under one should always sleep on their own flat, firm surface with no loose bedding. If space is that tight, a bigger tent or a pop-up bassinet is the fix, not sharing.
How do I keep the tent dark so my baby sleeps past 5am?
Choose a tent with darkened bedroom fabric, pitch with the bedroom facing away from the sunrise, and use a purpose-made breathable blackout cover designed for travel cots. Never drape a blanket or towel over the cot, which traps heat and restricts airflow. Expect to win an extra hour rather than a lie-in: dawn and birdsong still leak in.
