What TOG sleeping bag does your baby need in an air-conditioned UAE bedroom? A simple temperature chart, what to dress them in underneath, and how to tell if they are too hot.
It is 4am. The AC has been humming since bedtime, your partner likes the room at 19, you keep sneaking it up to 24, and now you are standing over the cot with your hand on the back of your baby's neck, trying to decide whether they need another layer or one less. Outside it is still 32 degrees. Inside, nobody can agree what the thermostat should say.
If this is you, you are in very good company. Almost every parent in the UAE goes through this, because most baby sleep advice was written for homes in the UK or Europe, where the worry is a cold house in winter. Our problem is the opposite: scorching heat outside, a cold, dry, air-conditioned bedroom inside, and a room that can swing several degrees between bedtime and dawn. So here is the guide we wish someone had handed us: what TOG actually means, what your baby needs at each room temperature, what goes on underneath, and how to know you have got it right without checking every hour.
TOG stands for Thermal Overall Grade, and it simply tells you how warm a fabric is. The higher the number, the warmer the sleeping bag. A 0.5 TOG bag is very light, a 1.0 TOG bag is light to medium, and a 2.5 TOG bag is a padded bag made for genuinely cold rooms.
The number describes the bag, not the room, so it only makes sense alongside two other things: how warm your baby's room is, and what your baby is wearing underneath. A 1.0 TOG bag over a short-sleeve bodysuit and the same bag over a long-sleeve sleepsuit are two very different outfits.
It is tempting to buy the warmer bag "just in case", especially when the AC makes the room feel icy to you. Resist it. Adults throw off the duvet when they get hot. Babies cannot, so the job of getting the weight right falls to us.
What TOG does a baby need with the AC on?
For most air-conditioned bedrooms in the UAE, a 1.0 TOG sleeping bag is right all year. Put a short-sleeve bodysuit underneath when the room is around 22 to 24 degrees, and a long-sleeve sleepsuit when the room runs cooler. Only go down to 0.5 TOG, or skip the bag, if the room stays warmer than 24 degrees.
Here is the general guide most sleeping bag makers use. Every brand's chart is slightly different, so check the label on your own bag:
Room temperature
Sleeping bag
What to wear underneath
Above 27°C
No bag, or 0.2 TOG
Nappy and a thin short-sleeve bodysuit
24 to 27°C
0.5 TOG
Short-sleeve bodysuit
22 to 24°C
1.0 TOG
Short-sleeve bodysuit
20 to 22°C
1.0 TOG
Long-sleeve bodysuit or sleepsuit
16 to 20°C
2.5 TOG
Long-sleeve bodysuit or sleepsuit
Please treat this chart, and every chart like it, as a reference and not a rule. Every baby is different, just like adults. My husband can be too hot at night and kick the covers off while I am under the blanket freezing, in the same room at the same temperature. Babies are exactly the same: some run warm, some run cool. Use the chart to choose a starting point, then watch how your baby responds and adjust from there. I know that can feel stressful when you just want someone to give you the right answer. Your baby is the answer, and the section below shows you how to read them.
The top and bottom rows rarely apply in a Gulf home. The middle three are where almost every UAE nursery lives, which is exactly why we made our 1.0 TOG bamboo sleeping bag at that weight. It comes in Frost Blue and Flamingo Pink, and now in two new colours, Sea Sage and Lavender Dreams. One bag, and you adjust with what goes underneath: a bamboo baby sleepsuit on the colder nights, a short-sleeve bodysuit on the rest.
What temperature should a baby's room be in the UAE?
The Lullaby Trust, the UK's safe sleep charity, recommends 16 to 20°C for a baby's room. Many UAE families keep nurseries warmer, often around 22 to 24°C, and that is fine as long as your baby is dressed for it: lighter layers and a lower TOG in a warmer room, so they never end up hot.
The real challenge here is not the number, it is the swing. A room can sit at 24 at bedtime, drop to 19 by 4am as the AC keeps cycling, then climb fast if there is a power cut or someone switches the unit off. And the number on the AC remote is not the temperature at the cot. It reads the air near the unit, which can be a few degrees different from the other side of the room.
So the most useful thing you can have in a Gulf nursery is a room thermometer at mattress height, near the cot, away from the AC and the window. Many baby monitors already show the room temperature, so check yours before you buy anything. Look at it at bedtime and once in the night for the first week. After that you will know your room, and deciding what your baby wears becomes a thirty-second job instead of a 4am worry.
How do you know if your baby is too hot or too cold?
Feel your baby's chest or the back of their neck, not their hands or feet. If it feels hot or sweaty, take a layer off. Cool hands and feet are completely normal in babies and do not mean they need more clothes. This is The Lullaby Trust's advice, and it is the single most reassuring check you can learn.
Signs your baby is too warm:
Damp hair or a sweaty neck
Flushed cheeks or a hot, clammy chest
Fast breathing or unusual restlessness
Signs your baby may be too cool:
The chest or back of the neck feels cool, not just the hands
Mottled skin on the body: a blotchy, lacy, slightly purple pattern
Two things matter even more in the Gulf. Babies do not need hats indoors, however cold the AC feels, because they let heat out through their head. And overheating is the bigger risk in our homes, not cold. If a well-meaning grandmother insists on a hat or an extra blanket, you are not being careless by saying no. You are following the advice. When in doubt, one layer less, then check again.
Where should the cot go in an air-conditioned room?
Put the cot where the AC does not blow straight onto it. A cot under the unit or in the line of a fan gets a constant cold draught across the baby's face and chest while the rest of the room stays warmer. The Lullaby Trust says a fan should never be aimed directly at a baby, and the same thinking applies to AC.
A few practical rules for Gulf bedrooms:
Keep the cot out of the direct airflow of the AC and away from the vent.
Keep it away from windows, where the glass heats the air in the afternoon and chills it at night.
If you cannot move the cot, angle the louvres up and away rather than switching the AC off, which lets the room heat up quickly.
Keep the cot clear: no blankets, pillows, bumpers or soft toys. The sleeping bag replaces the blanket completely.
That last point is the whole reason sleeping bags exist. The American Academy of Pediatrics (AAP) advises keeping loose bedding, including blankets, out of a baby's sleep space, and recommends a wearable blanket instead. If you have been tucking a blanket in until now, you have not failed. Most parents do exactly the same until someone tells them. Just swap it tonight.
When can a baby start using a sleeping bag?
A baby can sleep in a sleeping bag from birth, as long as the bag is made for their weight. The neck and armholes must fit snugly, so their head cannot slip down inside. Sleeping bags are sized by weight rather than age, and newborn sizes often start at around 4 kg, so always check the weight range first.
Our Essential sleeping bag comes in three sizes:
Size
Baby's weight
Baby's length
Small
6.5 to 9 kg
56 to 69 cm
Medium
8 to 14 kg
66 to 84 cm
Large
13 to 19 kg
84 to 102 cm
Our Small starts at 6.5 kg, so it is not designed for a newborn, and many babies do not reach 6.5 kg until somewhere around four to six months. That can be after swaddling has had to stop. So plan for the gap: swaddle in the early weeks, and if your baby is still under 6.5 kg when they show signs of rolling, use a newborn-sized bag with a weight range that fits them until they are big enough for the Small. Whatever you choose, fit by weight. Never size up for "room to grow" in the neck and arms.
At the other end, the Large carries on into toddlerhood, which helps in a cold AC room with a toddler who kicks off every cover.
Sleeping bag, swaddle, or weighted sleep sack?
A swaddle wraps a newborn's arms in to calm the startle reflex. A sleeping bag leaves the arms free and simply keeps the baby warm. The AAP advises stopping swaddling as soon as a baby shows signs of trying to roll over, and that is the moment to move into a sleeping bag.
Weighted sleep sacks are a different story. They are sold as helping babies settle, but the AAP says weighted swaddles and weighted objects are not safe for infant sleep, because pressure on a baby's chest can make breathing harder, and several big retailers stopped selling them in 2024. It is completely understandable to want anything that promises sleep when you are this tired. This is one to skip.
Our sleep bags and swaddle blankets are made for exactly that sequence: bamboo swaddles for the newborn weeks, then the 1.0 TOG sleeping bag once the arms come out. Both are bamboo and OEKO-TEX Standard 100 certified, and the sleeping bag has a YKK double zip with a long puller, so a 3am nappy change means unzipping from the bottom, not waking the whole baby up. If you want the design story, it is in our Essential sleeping bag launch post.
Can a sleeping bag help your baby sleep at night?
It can, as part of a bedtime routine. Newborns are not born knowing the difference between day and night, and that rhythm takes months to build. The NHS suggests a simple, soothing bedtime routine and keeping night feeds calm, dark and quiet, so your baby learns that night is different from day. Putting on the sleeping bag can become one of the cues that tells your baby the long sleep is coming.
Ours went like this, in the same order every night: a warm bath, a baby massage, milk, then into the sleeping bag and into bed. And I never used the sleeping bag for day naps. During the day Atlas napped close to me, swaddled when he was tiny, so the sleeping bag only ever meant one thing: night time, here comes the long stretch. I really believe that helped him learn the difference between a nap and the night.
Plenty of parents use a sleeping bag for naps too, and that is completely fine. It is the same safe way to keep a baby warm. Keeping it for nights is just one more cue you can use if you are trying to build that night-time rhythm.
How many sleeping bags do you actually need?
A minimum of two, and honestly, three is better. One on the baby, one in the wash, and one ready for the night that goes wrong. Because it will: a leaking nappy, reflux, or the kind of explosion parents call a poonami, sometimes two or three times in one night. With only two, you can be left with one in the wash and the other already soiled. In the UAE most of us are running a wash every single day anyway, and a third bag means you are never drying one under the AC at midnight.
You do not need a different bag for every season. In an air-conditioned home, one 1.0 TOG weight covers the year, and you change what goes underneath. If your baby moves up a size, buy the next size then, not before: a bag that is too big in the neck is not a safe bag.
The short version
For a UAE bedroom with the AC on, a 1.0 TOG sleeping bag covers almost every night. Change what goes underneath, not the bag: a short-sleeve bodysuit around 22 to 24 degrees, long sleeves when the room runs cooler. Treat any TOG chart as a starting point, because your own baby is the real guide. Keep a thermometer by the cot, keep the cot out of the AC's draught, check the chest or the back of the neck rather than the hands, and when in doubt, take a layer off. No hats, no blankets, nothing weighted. Keep two or three bags on rotation, and let the sleeping bag become part of a bedtime routine your baby can recognise.
And be kind to yourself. You will get it slightly wrong some nights, everyone does, and the fact that you are standing there at 4am checking is exactly what a good parent looks like. From one tired mum to another: you have got this.
Frequently asked questions
What does 1.0 TOG mean?
A 1.0 TOG sleeping bag is a light to medium weight bag, made for rooms of roughly 20 to 24°C. In the UAE, where most bedrooms are air-conditioned, it is the weight that suits most nurseries all year, with the layer underneath changed for warmer or cooler nights.
What TOG sleeping bag is best for air conditioning in the UAE?
A 1.0 TOG sleeping bag suits most air-conditioned UAE bedrooms year round. Pair it with a short-sleeve bodysuit when the room is about 22 to 24°C and a long-sleeve sleepsuit when it is cooler. Choose 0.5 TOG only if the room stays above 24°C.
Is 24°C too hot for a baby's room?
Not if your baby is dressed for it. At around 24°C, a short-sleeve bodysuit under a 1.0 TOG sleeping bag, or a 0.5 TOG bag, is usually right. The Lullaby Trust recommends 16 to 20°C, so in a warmer room keep the layers light and check your baby's chest or the back of their neck for sweating.
Is 28°C too hot for a baby's room?
A room at 28°C is warm for a sleeping baby. Dress them in just a nappy and a thin bodysuit with no sleeping bag, or a 0.2 TOG bag at most, keep air moving without a fan pointed at them, and check their chest or neck regularly. If you can, bring the room down a few degrees.
What should my baby wear to sleep with the AC on?
In a room of about 22 to 24°C, a short-sleeve bodysuit under a 1.0 TOG sleeping bag is usually right. If the room drops to around 20 to 22°C, swap to a long-sleeve sleepsuit under the same bag. Skip hats and blankets, and check the chest or the back of the neck rather than the hands.
Should my baby wear a hat to sleep in an air-conditioned room?
No. Babies release heat through their head, and The Lullaby Trust advises against hats for sleep indoors, however cold the AC feels. Use the right sleeping bag and layer underneath instead, and check the back of the neck to see if they are warm enough.
Can a 2 week old use a sleep sack?
Yes, if the sleep sack is made for their weight and the neck and armholes fit snugly so their head cannot slip inside. Many newborn sleeping bags start at around 4 kg. Many families swaddle in the early weeks instead and move to a sleeping bag once the baby shows signs of rolling.
Can I use a blanket instead of a sleeping bag?
The American Academy of Pediatrics advises keeping loose blankets out of a baby's sleep space, because they can cover the face. A wearable sleeping bag gives the same warmth safely, and it cannot be kicked off in the night, which matters in a room where the AC keeps cooling.
How many sleeping bags does a baby need?
A minimum of two, and ideally three: one being worn, one in the wash and one spare. Nappy leaks and reflux can happen two or three times in one night, so a third bag means you are never waiting for one to dry. In an air-conditioned home, one weight, usually 1.0 TOG, covers the whole year.
Is a TOG chart right for every baby?
No. A TOG chart is a general reference, and every baby runs slightly warmer or cooler, just like adults. Use the chart as a starting point, then check your baby's chest or the back of their neck and add or remove a layer to suit them.
Should my baby use a sleeping bag for naps?
You can. A sleeping bag is just as safe for naps as for nights. Some parents keep it for night-time only, so that putting it on becomes a cue that the long sleep is coming, which can help a baby learn the difference between a nap and the night.
What is the difference between a sleeping bag and a swaddle?
A swaddle wraps a baby's arms in to calm the startle reflex in the newborn weeks. A sleeping bag leaves the arms free and replaces a blanket. The American Academy of Pediatrics advises stopping swaddling as soon as a baby shows signs of trying to roll, which is when most babies move into a sleeping bag.
