hi,
having cold hands is not an indication that a person is cold - its a blood circulation thing! (I often have cold hands and feet even when I am in none airconditioned places!!) To see whether a child or baby is cold, I think you should feel the nap of their necks.....I agree, although the baby books say 16-20 degrees to prevent SIDs, that is very cold and hard to achieve in the tropics- I kept my son sleeping in an airconditioned bedroom at about 21.5 to 22 degrees (even today), he wears long sleeve tops and pants and a 1.0 tog grobag (anything more than 22 degrees he would wake up perspiring)....never bothered with humidifiers or bowls of water except when he had a nasty cold that resulted in a blocked nose....just make sure their cot/bed doesn't get the direct draft from the aircon.
