Sleeping Over at Granny's: Safe Sleep for Your Baby Away From Home

Where is the baby going to sleep?

It is the very first question anyone asks when the half-term invite lands, or when Granny starts dropping hints about Christmas. And the answer is usually "erm, in that travel cot your brother used in 2009, probably in the loft somewhere".

Here is the reassuring bit: the rules for safe sleep do not change just because the postcode does. Same baby, same basics. What changes is everything around them, the room, the cot, the people and the routine. So we have broken it down into the order you will actually meet it, from packing the car to that first wobbly night in a strange house. 🧳

Before You Go: Sort the Sleep Space First

Pack the cot before you pack the cute outfits. Honestly, it is the one thing you cannot improvise when you arrive at 7pm with an overtired baby.

If you are borrowing a travel cot, ask for it to be set up a few days early so someone can check it over. If it is a dusty loft find, give it a proper inspection:

• Every side locks firmly into place with a click, and the base sits flat.
• No rips in the mesh, no loose threads or gaps a little hand or foot could get stuck in.
• It still has its own original mattress, firm and flat, with no sagging or cracks in the cover.
• All the instructions or at least the model name, so you can look up how it is meant to fit together.

If anything looks dodgy, do not try to bodge it. It is much easier to bring your own.

A lightweight pop-up travel cot is one of those things you will use far more than you expect. Grandparents, weekends away, caravan holidays, even a nap at a friend's house. It folds down small enough to live in the boot.

Top tip: if you have a little one who is fussy about new places, set the travel cot up at home for a few naps beforehand. A familiar cot in an unfamiliar room is a lot less of a shock.

When You Arrive: Do a Quick Room Sweep

Grandparents' houses are full of love. They are also full of blind cords, hot radiators and handbags stuffed with paracetamol. Before you unpack, take five minutes to walk round the room where baby will sleep.

• Cot position: away from radiators, heaters and direct sunlight, and not right next to a window.
• Cords and wires: nothing dangling within reach, including blind cords, curtain ties, phone chargers and lamp cables.
• Shelves and furniture: nothing heavy on a shelf above the cot, nothing a standing baby could grab and pull in.
• Bags and medicines: kindly ask everyone to keep handbags, pill organisers and toiletries up high.

Ideally, baby sleeps in the same room as you for the first six months, wherever you are staying. So if you have been put in the spare room and baby in the box room, a gentle swap might be in order.

Unfamiliar rooms are often lighter than your nursery at home, especially with streetlights or early sunrises. A temporary blackout blind that sticks to the window glass is a game changer, and it means you never have to drape anything over the cot itself (please do not, covers can trap heat and block airflow).

At Bedtime: Keep the Cot Boringly Bare

This is where well-meaning relatives often get carried away. Out come the hand-knitted blankets, the cot bumpers from the 90s, the fluffy pillow "so she's comfy". Bless them.

The safe sleep basics are exactly the same as at home:

• Baby goes down on their back, every sleep.
• Feet to the foot of the cot if you are using a blanket, tucked no higher than the shoulders.
• A clear cot: no pillows, duvets, bumpers, positioners or soft toys.
• Only the mattress that came with the travel cot. Never add a second mattress, a folded duvet or a sofa cushion on top to make it "softer". The thin, firm mattress is the safe one.

That last point catches out so many families, so it is worth saying out loud to whoever is helping you set up. Travel cot mattresses feel thin to adults, but they are designed that way for a reason. If you want a proper fitted replacement, buy one made specifically for that travel cot's exact size, so there are no gaps around the edges.

Pack baby's own sleeping bag too. It smells like home, it is safer than loose bedding, and it is one less thing to negotiate.

And the room temperature? Older houses can be freezing, while some grandparents keep the heating cranked up to tropical. Aim for somewhere between 16 and 20°C. A small room thermometer you can pop on the bedside table takes the guesswork out of choosing the right sleeping bag TOG.

Through the Night: Plan for the Wobbly Bits

The first night somewhere new is rarely the smoothest. Baby might wake more, feed more or just want to check you are still there. That is completely normal, and it usually settles after a night or two.

A few things that help:

• Keep the routine you know: same bath, same song, same sleeping bag, same white noise if you use it. Familiar cues travel well.
• Bring a portable monitor: if the evening carries on downstairs, you will want ears (and eyes) in that room.
• Be wary of the sofa: after a long day and a big dinner, it is very easy to doze off with baby on your chest. Falling asleep with a baby on a sofa or armchair is one of the riskiest sleep situations, so if you feel yourself drifting, pop baby back in the cot.
• Alcohol and bed-sharing do not mix: if you have had a drink at the family party, baby sleeps in their own cot, full stop.

Many home baby monitors rely on your own Wi-Fi, which is a faff to set up at someone else's house. A plug-and-play monitor that pairs straight to its own screen works anywhere, from Granny's spare room to a holiday cottage with patchy signal.

If anything about your baby's breathing, temperature or general behaviour worries you while you are away, do not wait until you get home. Call 111 or speak to a GP, wherever you are in the country.

The Morning After: Make Next Time Easier

You survived! Maybe you even slept a bit. ☕

Before you pack up, have a think about what worked and what did not. Was the room too bright? Too cold? Did the borrowed cot creak every time baby rolled over? Jot it down in your phone, because you will absolutely forget by Christmas.

If family visits are going to be a regular thing, it might be worth leaving a "Granny's house kit" there: a travel cot, a spare sleeping bag and a room thermometer that just live in the cupboard. Grandparents often love being asked to chip in for these, so they are perfect additions to your BubsNest wishlist. Much more useful than another pair of tiny shoes.

The short version? New house, same rules. Back to sleep, clear cot, firm flat mattress, comfy room, you nearby. Get those right, and the rest is just a lovely family sleepover.
