Most moms have experienced a "Calgon, take me away" moment. It's 5 p.m. — the kids are crying, mommy still hasn't showered, dinner is burned, and dad is out of town. Every now and then a mom can't handle the heat and needs to get out of the kitchen before her last nerve fizzles. Cooling down and gathering oneself is an art. When I reach the end of my rope, I take deep breaths and pray to God for patience. Humming a tune helps calm me and can often have a similar effect on my tots, too. What do you do to keep your cool?
