Living in Canberra the overnight lows are pretty damn chilly - like -4 today - I leave ours on 13 overnight - sounds low but believe me it does kick in.

Anyway, I put the vapouriser on in our room for the last couple of weeks and it has been great - I think I am getting addicted to the white noise of it bubbling away.

Me too Kimbaz - 2 other kiddies in the house - can't afford to lose anymore sleep than necessary!!!
