chilly is the right answer. 18 to 21 degrees C for babies and children toddlers.
That's not just a guess, though. Science backs it up.
Why does it matter?
As you go through your day, your body temperature goes up and down. When you get sleepy, your temperature starts to go to sleep.
A warm room prevents it from reaching its optimal sleep temperature, causing a restless night sleep and even insomnia. If you wake up sweaty, that's a sure sign that your room is too warm – or you're using too many blankets.
Sleeping with the room too cold, though, is not good for sleep either.
