Ideal temp is 23-24deg on normal aircon.. But frankly speaking, depends on your aircon.. My gal's room 25deg very cold, my room 20deg hot like one kind.
Heard before, best is 27deg but what's the point if you on 27 deg, must as well just on fan.. was my thinking..
Oh ya, you dress alittle too much for your boy oredi .. Does he drink much water? Better drink more to cool down body..
Fever is a symptom, not a disease. It is the body's normal response to infections. Fever helps fight infections by turning on the body's immune system. The usual fevers (100 to 104°F, or 37.8 to 40°C), which all children get, are not harmful. Most are caused by viral illnesses; some are caused by bacterial illnesses. Teething does not cause fever.
