The birth of your baby brings many new challenges, not least ensuring safe and healthy sleep. A sleep sack is an essential item in your newborn's bedding. It provides a safe sleeping environment and helps to optimally regulate your baby's body temperature throughout the night. In this article, I'll explain why your baby sleeps in a sleep sack and how a sleep sack with feet increases mobility as your child gets older.
Safety and warmth during baby sleep
A sleeping bag replaces traditional blankets, which can pose a suffocation risk, especially in the first few months after birth. Newborns tend to move around a lot in their sleep and could easily get trapped under a loose blanket. A well-fitting sleeping bag prevents this risk by keeping your baby warm and secure without the need for additional blankets. It also allows for even heat distribution, ensuring your baby stays consistently warm all over without overheating or getting too cold.
Determining the correct sleeping bag size
The correct size sleeping bag is crucial for your baby's safety and comfort. Here are some simple rules of thumb for determining your baby's sleeping bag size:
- Sleeping bag size : Choose the sleeping bag size by adding 10 to 15 cm to your baby's body length, measured from the head. These extra centimeters ensure that your baby has enough room to stretch and move comfortably without too much space to slip into.
- Sleeping bag with feet : The size of the sleeping bag with feet should correspond to your baby's body length, without any extra centimeters. This ensures that your baby's feet are properly positioned and they can move freely without the sleeping bag being too long.

Selecting the right material
When choosing a sleeping bag, make sure it's breathable and temperature-regulating. These properties are important to prevent overheating and maintain a constant body temperature while you sleep.
What does TOG actually mean?
TOG stands for "Thermal Overall Grade" and is a unit of measurement that measures the thermal resistance of textiles. This value indicates how well a sleeping bag can keep your baby warm in different ambient temperatures. The higher the TOG value, the warmer the sleeping bag. Choosing the right TOG value is crucial to ensure your baby neither overheats nor gets too cold, especially while sleeping.
TOG chart for baby sleeping bags
- 0.5 TOG : Ideal for hot summer nights and room temperatures above 22°C.
- 1.0 TOG : A lightweight sleeping bag, suitable for room temperatures between 18°C and 24°C.
- 2.5 TOG : Optimal for cooler environments with temperatures between 16°C and 20°C.
- 3.5 TOG : Thickly lined, for temperatures below 15°C, to keep your baby warm.
The recommended room temperature for a nursery is between 16°C and 18°C, creating optimal sleeping conditions for your baby. By choosing the TOG rating according to the room temperature, you help your baby enjoy a comfortable and safe night's sleep. Brands like emma & noah offer a variety of sleeping bags with different TOG ratings to meet your baby's needs in every season.
Sleeping bags with feet – ideal for active babies
As babies get older and begin to explore their surroundings more, a footed sleeping bag can be especially practical. This type of sleeping bag offers the security and warmth of a traditional sleeping bag, but allows for greater freedom of movement. This is particularly advantageous if you carry your baby in a baby carrier to help them fall asleep.
