Amen to that, sister.

Last night we had the reverse problem - humidifier plus kids playing with the heating controls during the day meant his room was a little sauna!!! Sigh, can't get it right!

We used a wheat bag. Only takes 1 min in the microwave and stays warm for awhile. We placed it where her head and shoulders would go and just whipped it out before putting her back to bed.
