I am always cold so when my kids come up to me I put my cold hands on them to warm up my hands. It causes them to squirm. we both laugh. It is a little mean but then they come up to me and say I am too hot you can put your hand here (usually arm). That is my confessiopn of torturing my kids how do you do it?
I put ice cubes down DS's shirt, especially when he is playing one of his video games. Don't worry, he is very good at getting me back. He will crawl into bed with me in the early (I mean before the sun early) am and put his ice cold blocks that he calls feet on my back!
