Check your baby and the thermostat to know if your little one is too cold at night. If any of the following rings true, chances are your little one is feeling chilly: Room temperature is 19 degrees Celsius or lower. Baby’s cheeks, neck, arms, or legs are cool to the touch. Baby’s skin is blotchy or pale. They seem overly sleepy or are hard to rouse. Baby is extra fussy or wakes up more frequently than usual. To warm your baby up, try some skin-to-skin snuggles and adjust the thermostat so the temperature of your little one’s room is between 20 and 22 degrees Celsius. At the same time, swap out your warm weather swaddle for one that’s lightly insulated with a TOG rating of 2.0, like the Comforter Sleepea.
