Singapore is pretty humid already (sometimes even up to 97% humidity), so if you leave the windows open and turn on the fan, there’s no need for a humidifier. Stay away from aircon, which dries the air + the cold air will irritate your child’s throat and worsen the cough
I use a humidifier but in air con room, it's fine. Haven't tried it in non air con room but in SG the humidity is already quite high.
