Yep, even though it has an automatic shut off I unplug it before leaving for work. When I get home I crank the A.C. in the bedroom and plug the pad back in.
Yes she definitely loves it. You might think twice though about leaving it on when you're not home. I had a neighbor once who had their electric blanket catch fire while they were in the shower and burn the house down. A heating pad really isn't meant to stay on all day.
Yes, it looks like she loves to sleep on her heating pad just like four boys from NH. Moritz on the other hand uses to sleep beside the heating pad I've bought for him last winter.
Since I set the central air for the bedroom VERY cool for sleeping, I've started leaving a heating pad on the bed for Claire. Do you think she likes it?
