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

If you’ve recently had a baby, you’ve probably searched the internet for ways to help your little one sleep better. There’s so much information out there, it’s easy to feel overwhelmed. That’s why Patricia, certified sleep coach at Bureau van Slaap, is here to clarify things. She shares 5 common baby sleep myths and what parents should actually focus on. 1. Your baby needs to sleep according to a strict schedule Online and in parenting books, you’ll find plenty of daily sleep schedules: a short morning nap, a long midday nap, possibly a late afternoon nap, and bedtime at 7 PM. While that sounds ideal (because it gives you predictability), most babies don’t follow such neat patterns. Some days the morning nap is short, other days it’s the longest. Some babies only take short naps all day. That’s why at Bureau van Slaap, we work with wake windows instead of fixed schedules. A wake window is the amount of time a baby can stay awake between naps. These windows vary by age and adjust as your baby grows. Putting your baby down at the end of their wake window makes it easier for them to fall asleep and rest longer. 2. Your baby should nap in the light during the day You’ve probably heard that your baby should nap in daylight during the day and only sleep in the dark at night — to help them learn the difference between day and night. This advice only applies to the first 6 to 8 weeks, while your baby is still developing a circadian rhythm. After that, it’s perfectly fine (and often helpful!) to let your baby nap in a dark room. Light signals the brain that it’s daytime and time to wake up. So for longer, more restful naps, darken the room from about 8 weeks onwards. 3. Babies shouldn’t sleep too much during the day People often say: “Your baby wakes up at night? Let them nap less during the day!” Unfortunately, the opposite is true. A baby who doesn’t get enough daytime sleep can quickly become overtired — and overtired babies actually sleep worse at night. Good daytime sleep supports better nighttime sleep. And don’t worry, most babies won’t sleep too much. Instead of counting hours, observe your baby: are they waking up happy, growing well, and hitting milestones? Then they’re likely getting the sleep they need. 💡 Pro tip: Try not to let a single nap last longer than 2.5–3 hours — save the long stretches for nighttime. 4. A later bedtime means your baby will wake up later Many parents with early risers (babies waking before 6 AM) are told to try a later bedtime. But keeping your baby awake too long in the evening leads to overtiredness, which actually increases the chance of early wake-ups. Sometimes, a later bedtime can help, but only if your baby has an extra late nap to support staying up longer. Otherwise, a later bedtime without added rest can backfire. And remember: early waking can have many causes — like hunger or a room that’s too bright. At Bureau van Slaap, we’re happy to help you figure it out. 5. Babies sleep better in their own room In the early months, most babies sleep in their parents’ room. It makes night feeds easier and supports bonding. Later on, some claim babies sleep better in their own room. But honestly? It depends on your child. If co-sleeping works for you and everyone’s sleeping well, there’s no need to change it. Around 6 months, many parents notice they start waking each other more easily. If that’s happening, it might be time to transition to separate rooms. But if you’re all sleeping well together — no need to rush it Need help with your baby's sleep? Send us an email — we’re always happy to think along with you!

TOG, or Thermal Overall Grade, is a measure of the insulating value of bedding. The lower the room temperature, the higher the TOG value should be. This system ensures that your baby sleeps comfortably, which is crucial for both your sleep and your baby’s. Here’s a tip: don’t add TOG values together, as extra layers create additional warmth due to the insulating air layer between the fabrics, which is not counted in the TOG rating. Which sleeping bags are available? At Jollein, you’ll find a range of sleeping bags that perfectly meet your baby’s needs, no matter the season or their age. Choose the ideal sleeping bag for your little one and ensure they enjoy a good night’s sleep! Newborn Cocoon / Wrapper This cocoon is perfect for newborns aged 0-3 months. It provides warmth and comfort, helping your baby feel secure and cosy. Summer Sleeping Bag With a breathable, lightweight fabric, these sleeping bags are perfect for warm summer nights. They keep your baby cool and comfortable. Made from airy muslin or stretchy jersey, these sleeping bags have a TOG value of 0.5—ideal for those warm summer evenings! Sleeping Bag with Removable Sleeves This versatile sleeping bag is ideal for any season. With a TOG value of 3.5 for winter and 2.5 for spring and autumn, it’s the perfect solution for active little ones. Do you prefer the version with a round or straight bottom? What size sleeping bag does my baby need? To choose the right sleeping bag, it’s important to measure your baby’s length. Simply lay your baby on a flat surface, such as a soft mat or bed. Make sure they’re lying straight with their arms by their sides. Use a flexible measuring tape, starting at the top of their head and measuring straight down to their heel. This will give you your baby’s total length. Compare the measurement with our size guide and choose a size slightly larger to ensure your baby has enough room to move, but without too much extra space or gap around the neck. The guide below is for reference, so always consider your baby’s length. Jollein offers four sizes of sleeping bags: 60 cm: Suitable for newborns from birth to around 3 months. 70 cm: For babies aged 3-6 months. A great follow-up to the Newborn sleeping bag! 90 cm: Suitable for babies from around 6 to 18 months. 110 cm: For toddlers from 18 months until they no longer need a sleeping bag. Need a Little Help?

As a parent, you may sometimes wonder if your baby is too hot or too cold. It can be tricky to gauge, especially for newborns. Babies are still learning to regulate their body temperature, so it’s important to ensure they are neither too warm nor too cold. In fact, it’s generally better for your baby to be slightly too cold than too warm! Luckily, there are guidelines in place to help you dress and tuck in your little one, so they can sleep safely without overheating or getting too chilly. In this blog, we’ll explain everything you need to know about the TOG value and how it can help ensure your baby sleeps comfortably. Common Sense: Checking Your Baby’s Temperature As you know, a too-warm bed can be uncomfortable. You may feel overheated and need to kick off the covers. Your baby can’t do this on their own, so it’s important to check them regularly. Does their head feel too warm? Are their feet or neck too cold? Are they sweaty or clammy? These signs can help you gauge their comfort. It’s especially important to keep an eye on your baby’s temperature if they have a cold or fever. The heat needs to escape, so ensure they’re not too bundled up. It’s also helpful to regularly check the room temperature. Remember: it’s always better for your baby to be slightly cooler than too warm. Why Keeping Your Baby Cool is Important Research shows that babies can overheat if their bed is too warm or ‘too full.’ Babies who are wrapped too snugly or who sleep with pillows and heavy duvets may end up with their face against bedding that restricts airflow. Overheating can increase the risk of Sudden Infant Death Syndrome (SIDS), so it’s vital to avoid excessive warmth. If your baby is too warm, their body temperature can rise to unhealthy levels, especially in a heated room. Keep the room temperature around 18°C (65°F)—this is considered the ideal temperature for your baby to sleep safely and comfortably. Understanding the TOG Value: A Guide to Baby Bedding When it comes to making sure your little one is comfortable, using your common sense is the best approach. But there’s also a useful tool to help you manage temperature: the TOG value. The TOG (Thermal Overall Grade) value is a rating system that indicates how well a fabric retains body heat. The higher the TOG value, the better it insulates. So, if the room is cooler, you’ll need bedding with a higher TOG. Conversely, in warmer rooms, a lower TOG value is better. TOG values typically range from 0 to 4, with higher numbers suited to colder environments. It's important to note that TOG values are designed for use in room temperature settings and should not be applied to outdoor conditions. TOG Rating Explained: TOG 0.5 – 1.0: Ideal for warmer rooms (20°C and above) TOG 1.5 – 2.5: Suitable for room temperatures around 18°C TOG 3.0 – 4.0: Perfect for cooler environments (below 18°C) When to Use TOG in Baby Bedding You can find TOG ratings on baby sleeping bags, swaddles, blankets, and other bedding products. Make sure you check the TOG value before purchasing to ensure your baby will be comfortable, no matter the temperature. TOG Value and Baby Sleep Safety: A Final Thought While the TOG value is a helpful guide, your own judgement and regular checks on your baby’s comfort are essential. Babies can’t regulate their body temperature like adults, so it’s important to create the ideal sleep environment for them. A room temperature of 18°C is generally perfect, and using the appropriate TOG-rated bedding will help keep your baby safe, comfortable, and able to get the rest they need. Note: You should not add TOG values together. This is because of the insulating air layer between two layers of fabric. This air layer always creates extra warmth. Trust your instincts and use your common sense.
