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:
-
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.
