How to dress baby for the night according to the room temperature?

Knowing how to dress your baby for the night is a question that all new parents ask themselves. Covering your child too much can lead to overheating, while a baby who is not covered enough may sleep poorly or even fall ill. One of the key factors to take into account is the room temperature. In this article, we guide you step by step in adapting your baby's outfit according to different temperatures, in order to ensure their comfort and safety.

🌡️ What is the ideal temperature in the baby's room?

Before choosing how to dress your baby, it is essential to know the ideal temperature for sleeping. Pediatricians recommend a temperature of 18 to 20°C in the baby's room, as this promotes restful sleep and limits the risk of sudden infant death syndrome.

To measure the temperature, the ideal is to use an ambient thermometer fixed in the room, at bed height.
