Thanks nic. I would prefer not to either. I don't have a humidifier though any ideas where these are sold? Big W or only chemists. I have been buring eucalytus in my oil burner but that only last a little while and I can't have it on when she's aseel as I am frighten of the candle. I have been using baby vicks though, but it just seems to run out as such in the early hours of the morning. Thanks again.
