The Jollein Sleep Guide | TOG value & safe sleep for your baby A good night’s sleep is just as important for your baby as it is for you. But how do you make sure your little one stays warm without overheating? And what do all those TOG values actually mean?In this sleep guide, we explain how to let your baby sleep safely and comfortably. What is TOG? TOG stands for Thermal Overall Grade and indicates how warm a sleep product is. Think of sleeping bags, blankets and footmuffs. The higher the TOG value, the more heat the product retains. TOG helps you make a conscious choice for what your baby needs during sleep, based on the room temperature and the season. It’s important not to simply add TOG values together. The layer of air between clothing and bedding creates extra warmth, which means the calculation may no longer be accurate. The ideal temperature in the baby’s room The recommended temperature for a baby’s room is between 16 and 20°C. Within this range, you can use TOG values and clothing layers to fine-tune what your baby needs. Not sure? Always feel your baby’s neck or back. This is the best way to tell whether your baby feels too warm or too cold. Which TOG value suits which temperature? Use the table below as a guideline, but always keep an eye on your baby and their comfort. 🧡Tip: slightly cooler is better than too warm. Overheating can lead to restless sleep.   Why a sleeping bag is a safe choice A sleeping bag is one of the safest ways to keep your baby warm while sleeping. Unlike loose blankets, a sleeping bag cannot cover your baby’s head and keeps them comfortably wrapped all night long. At Jollein, you’ll find sleeping bags for every season and age: Summer sleeping bags (TOG 0.5) Sleeping bags with removable sleeves for spring and autumn  4-season sleeping bags that can be adjusted all year round Newborn sleeping bags for extra comfort during the first weeks – [add hyperlink to Newborn Cocoons collection] This way, you create a safe and familiar sleeping environment every night. Making the baby bed safely A good night’s sleep starts with a safely made bed. Keep it calm and clutter-free: Use a firm mattress with a well-fitting fitted sheet Avoid loose items such as pillows and soft toys Prefer a sleeping bag over loose blankets Do you still want to use a sheet or blanket? Tuck it in tightly under the mattress so your baby cannot slide underneath. Material also matters: Thicker, padded blankets are suitable for cooler rooms Thin (muslin) blankets are more comfortable at higher temperatures And most importantly: trust your instincts. Feeling your baby’s neck and observing their behaviour will tell you a lot.

It’s freezing outside, the heating goes up a notch and all you want to do is crawl under a thick duvet yourself. But how do you make sure your little one stays nice and warm at night, without overheating? Every season it’s a bit of a puzzle with layers. No worries! We’re happy to help you with a few practical tips, so you can both enjoy a good night’s sleep. Dreaming big since 1973 At Jollein, we’ve been working on the perfect sleeping bag since the 1970s. It all started with a simple idea: babies sleep more peacefully (and safely!) in a sleeping bag. Many years later, we’ve used that expertise to develop the perfect sleeping bags that do exactly what they’re meant to do: provide comfort. We know which fabrics feel soft on delicate baby skin and which thickness you need at what time. Whether you choose a sleeping bag or a traditionally made-up crib: we’ve got you. The TOG value: your new best friend You’ve probably seen the term before: TOG value. It may sound technical, but it’s simply a guide to how warm a sleeping bag or blanket is. In winter, we usually aim for a total of 2.5 to 3.0 TOG. How you build that up depends on the room temperature: Colder than 18°C? Choose a winter sleeping bag with sleeves, combined with pyjamas and a bodysuit, or use a sheet with a warm blanket. Around 20°C? A winter sleeping bag with just a bodysuit, or a sheet with a single blanket, is often enough. Our tip: Not sure? Feel your baby’s neck. Does it feel comfortable? Then you’re good. Does it feel clammy or sweaty? Time to remove a layer. Cold hands are common in winter and usually nothing to worry about. Sleeping bag or made-up crib? Every baby (and every parent) is different. Some swear by a sleeping bag, while others prefer a snugly made-up crib with a sheet and blanket. The sleeping bag | Ideal for active babies who ‘walk’ through the crib in their sleep. Our winter sleeping bags often have detachable sleeves – super handy when temperatures suddenly rise. Sheets and blankets | A sheet gives a cosy, secure feeling, especially when the crib is tucked in tightly. In winter, add a beautiful knitted blanket on top for extra warmth. Mix, match and unzip Let’s be honest: looks matter too. Whether you go for a complete look or love to mix things up, our prints are made to combine. From dreamy Flower Fairies and cute Animal Friends to calm Leafy Dreams or cheerful Tiny Park. A subtle printed sheet peeking out from under a plain blanket? There’s always something that fits perfectly in your nursery. Safety above all The most important thing is that your little one sleeps safely. Using a sheet and blanket? Always make the bed ‘short’: your baby’s feet near the foot of the crib, so they can’t slip under the covers. Using a sleeping bag? Make sure it’s the right size so the neckline fits snugly. Quick check: Choose your style: the ease of a sleeping bag or the snug feel of a blanket? The right size: the neckline shouldn’t be too wide. Build layers: combine a thin bodysuit with a sleeping bag, rather than one very thick item. Trust your instinct: you know your baby best. If they sleep well, you’re doing great. Have questions about which combination works best in your nursery? We’re happy to help. For all the first nights – and many more to come: sleep well! Love,Jollein

The lower the room temperature, the higher the TOG rating should be. This system ensures your baby sleeps comfortably, which is essential for your rest and theirs. A tip: don't add up TOG ratings—extra layers create warmth from the air between fabrics, which isn’t included in the rating. Which sleeping bags are available? At Jollein, you’ll find a selection of sleeping bags that match your baby’s needs, no matter the season or age. Choose the ideal sleeping bag for your little one and ensure restful nights! Newborn Cocoon / WrapperThis cocoon is perfect for newborns aged 0–3 months. It offers warmth and comfort, helping your baby feel safe and secure. Summer Sleeping BagMade from breathable, lightweight fabric, these sleeping bags are ideal for warm summer nights. They help keep your baby cool and comfortable. These sleeping bags are made from airy muslin or stretchy jersey and have a TOG value of 0.5—perfect for warm summer evenings! Sleeping Bag with Detachable SleevesThis versatile sleeping bag is perfect for any season. With a TOG rating of 3.5 for winter and 2.5 for spring and autumn, it’s the ideal solution for active little ones. Will you choose the version with a rounded or straight bottom? Which size sleeping bag does my little one need? To choose the right size, it’s important to measure your baby’s length. Lay your little one on a flat surface, like a soft mat or bed, and make sure they are lying straight with their arms at their sides. Use a flexible measuring tape and start at the top of the head, measuring straight down to the heel. This gives you the total body length. Compare it to our sizing chart and choose a size slightly larger so your baby has room to move—but not so much that the neckline is too loose. The table below is a guideline—always consider your baby’s length. Jollein offers four sleeping bag sizes: 60 cm: Suitable for newborns from birth to about 3 months. 70 cm: For babies aged 3–6 months. A great follow-up after the newborn sleeping bag! 90 cm: Suitable for little ones aged around 6 to 18 months. 110 cm: For toddlers aged 18 months and up—until they no longer need a sleeping bag.
