| put a bowl of water (warm water if you like) under your bub's crib. it will keep moisture in the air.
I could be wrong, but i seem to remember the "ideal" temp being quite a bit lower than 25oC ... i remember Matilda nursery being closer to 18 (tho that could be wrong too). I do know the cooler the better tho. With that said, i could never "achieve" an ideal temp in the house. in summer (apr-end of sept) was always warm, even with a/c (we have a big bedroom). just make sure bub is not over dressed ... when we brought our son home (also a sept baby), he usually just wore a onsies adn then was swaddled in a receiving blanket.
i'd be worried that a Humidifier (hot or cold) would generate extra mold in the room. a bowl of water can be contolled (just dump it out) ... we still use a bowl (or fill the bathtub) in teh winter when it gets more dry.
you're right tho ... a/c 24/7 isn't healthy ... but in hk there's not a lot of choice ...esp with the pollution as bad as it is at the mo; it's not as tho i'd want to open up the windows and say "ahh"
