Find the perfect baby sleeping bag – The best choice for safe baby sleep

A good night’s sleep starts with the right baby sleeping bag. A baby sleeping bag is a safer alternative to blankets, as it reduces the risk of overheating and overcovering. But which size is right? Should you choose a baby sleeping bag with feet or a classic model? And which material offers the best sleep comfort? Find clear answers and expert tips for choosing the ideal sleeping bag to support safe and restful baby sleep.

1. What is the right size for a baby sleeping bag?

A baby sleeping bag should fit snugly for safe sleep, but still offer enough room for your baby to move freely and sleep in comfort. Choosing the right size supports both security and freedom of movement.

How to choose the right size baby sleeping bag size:

Use this simple formula: baby’s height from shoulders to toes + 10 centimeters = the ideal baby sleeping bag size.

There should be about 10 centimeters of space between your baby's feet and the end of the baby sleeping bag to allow for freedom of movement and comfortable sleep.

👉 Important: Never choose a sleeping bag that is too large. If the fit is too loose, the neckline may slip over your baby’s face, increasing the risk to sleep safety. Always choose the right size to support safe baby sleep and proper positioning.

2. Baby sleeping bag with feet or a classic sleeping-bag/ball-shaped sleeping-bag?

Whether you should choose a classic baby sleeping-bag or one with feet depends on your baby’s sleeping habits:

✔ Ideal for newborns and premature babies

✔ More freedom of movement for legs and arms

✔ Prevents the blanket from slipping and strengthens leg muscles

👉 Tip: Up to around 18 months, a classic ball-shaped sleeping-bag is often the best choice. After that, many children benefit from greater freedom of movement in a sleeping-bag with feet.

3.  TOG value explained: Which baby sleeping bag for which room temperature?

The TOG value shows how warm a baby sleeping bag will keep your child. Depending on the room temperature, you should choose the appropriate TOG value to ensure safe and comfortable baby sleep. Use our TOG value table as a helpful guide to find the right sleeping bag for every season.

👉 Tip: To check if your baby is at the right temperature, feel the back of the neck. If it feels warm and dry, everything is fine. If it feels too hot, open the slits and check again after a few minutes to maintain safe baby sleep.

It’s all about proper ventilation!

The ventilation slits in the Träumeland sleeping-bag make it easy to regulate the temperature. If your baby gets too warm, you can open the slits – within just 5 minutes, the temperature inside the sleeping-bag will drop by around 3°C. This means you don’t have to change your baby’s clothes – you can simply adjust the warmth with ease. If it gets too chilly again, just close the vents to ensure your baby stays comfortably warm.
