How do I grant my parent temporary power of attorney over my kids? - missouri temporary visitor drivers license

My children go to visit my parents in Michigan, while I live in Missouri. It's only for a month, but my parents want the power, if they should go to the hospital for something. How do I do that? As soon as possible. I forget everything and go on Saturday.
