Room temperature in kids room

What’s the general temperature you keep it ?

I’m noticing my sons room gets to be in the 60s as low as 62 Sometimes.

If I put fleece on him he sweats but if I put him in say shorts and a long sleeve like now he gets cold but pants he gets hot he always kicks off the blankets

I don’t feel comfortable running a space heater if there’s no supervision. Turning up the heat doesn’t work that room just doesn’t get heat the same.

Suggestions ? (Also he’s 2 if that’s of help)
