Knowing how to dress your baby at night is essential to ensure their comfort, restful sleep, and stable body temperature. Overdressing your baby can cause overheating, while too light clothing can make them feel cold. Here is a practical guide to adapt your infant's nightwear throughout the year, according to temperatures and seasons.
The ideal baby room temperature
The room temperature should be between 18 and 20 degrees. This temperature range promotes baby's sleep without risk of overheating. A thermometer is essential to check that the room is neither too cold nor too hot.
The role of sleeping bags and the TOG rating
The sleeping bag (or turbulette) is a secure nightwear. It replaces the duvet or the blanket and comes in different TOG ratings, depending on the season:
-
TOG 0.5 to 1 : for summer or high temperatures
-
TOG 1 to 2 : for intermediate seasons (spring, autumn)
-
TOG 2.5 to 3: for winter or cold rooms
Choosing the right TOG allows baby to stay warm and cozy, without the risk of excessive sweating.
