Adjust the temperature of the room
Make sure you don't overheat your baby's environment at night: it should be between 16 and 20 degrees Celsius in his room, the ideal temperature being around 18°C. Also keep your baby's bed away from the radiator. If you are in doubt, don't hesitate to check if your baby is cold at night: don't rely on his hands, which are often colder than the rest of his body, but slide a finger over his skin on his stomach or chest. If her skin is cold, add a layer of clothing. A tip to make sure the room is the right temperature: install a thermometer in the room, which will make it easy to check whether or not you need to turn up the heat.
Get to know the TOGs
To choose the right sleeping bag (also known as a "turbuette" in french), use the TOG, the heat rating that determines the thermal resistance of a fabric, which is most often indicated on the label of the sleeping bag. The higher the TOG, the warmer the sleeping bag will be for your baby: in winter, opt for a sleeping bag with a TOG 2 - or TOG 3 if the room temperature is below 18 degrees - to ensure your baby is warm and soft.
Put together the perfect sleepwear
To ensure comfortable nights and keep your baby warm in winter, rely on three good basics:
a long-sleeved cotton bodysuit. For the smallest babies, opt for a double-breasted bodysuit in the front, which is easier to put on.
a sleeping bag: these one-piece pyjamas, which also cover the baby's feet, are ideal for sleeping.
a sleeveless sleeping bag, TOG 2 or 3. If your baby doesn't like to sleep in a sleeping bag (which often happens when they learn to sit up on their own and the sleeping bag hinders their movements), choose an over-sleeping bag, which will give them more freedom of movement.
