TOG rating for baby sleeping bags: which sleeping bag to use when?

by Tess Daems on Feb 16 2026

A good night's sleep is priceless, both for your baby and for you. Safety and comfort are central to that. A sleeping bag for your baby is not only safer than a loose blanket, but often more convenient to use as well. But how do you choose the right sleeping bag exactly? And what role does the TOG rating play? In this guide, we explain everything so your little one can sleep soundly and safely, all year round.

Why a baby sleeping bag?

Sleeping bags are much safer than loose blankets. They prevent your baby from wriggling under a blanket or rolling onto their stomach, significantly reducing the risk of cot death and other accidents. But the comfort aspect is just as important. Active sleepers who kick off their blanket stay warm and calm thanks to a sleeping bag.

Putting on a sleeping bag can also become a fixed part of the bedtime routine: the signal that it is time to go to sleep.

Even when away from home, a familiar sleeping bag offers reassurance and convenience, making it easier for your child to relax and fall asleep.

What is the TOG rating of a sleeping bag?

The TOG rating is a handy indicator of the thermal insulation of a baby sleeping bag. The higher the TOG rating, the better the sleeping bag retains heat.

Thanks to the TOG label, you can tell at a glance whether the sleeping bag is suitable for the room temperature and the season.

Here is how it works in practice: at a room temperature of about 18 degrees, for example in spring or autumn, it is best to choose a sleeping bag of 1.0 TOG in combination with pyjamas and, if necessary, an extra blanket. In the cold winter months, when the room is 14 to 16 degrees, a warm sleeping bag of 2.5 to 3.5 TOG is ideal, combined with pyjamas and underwear. During warm summer nights, around 24 degrees, a lightweight sleeping bag of 0.2 to 0.3 TOG or a short jumpsuit is sufficient.

Thanks to the TOG rating, you can easily match the sleeping bag to the season, but don't forget to also pay attention to other factors such as the size and type of sleeping bag. Note: there are no standards for TOG ratings. Every brand uses this in its own way. TOG ratings only provide an indication. Always check your child's temperature yourself.

The right size of baby sleeping bag

The size of the sleeping bag is crucial for safety. A sleeping bag that is too large can be dangerous, because your baby could sink down into it. لذلك choose a sleeping bag that fits your child's length exactly. Some sleeping bags have a zip that opens from top to bottom, so you can be sure your baby cannot open the sleeping bag themselves. That way, you combine safety with practical convenience.
