My family calls me Chelle, although my Dad called me Hoppy Toad for a while. My children are called Jo (Shauna), M.O. (Emily), Tater (Taylor), and Dilly Doodle (Dylan). My Dad was Fritz and my sister is Coley.
My Aunt Karen is called "Pie Face" by her hubby (cause her face is so round). She calls him Smoochy. He says it with so much love on his face and in his eyes. I can't help but smile when I hear/see this exchange between them.
My FIL calls the three DILs "My Girls"
