As it turns out, Brock and I are sick at the same time (with different things, of course). As he asks me to get him some crackers and a drink, he comes into the kitchen where I am and gives me a big hug. He says, "Thanks for taking care of me, Mama." I told him that's what moms do, and he says, "I know, but by you taking care of me when I'm sick, you might get worse because you're not resting."
Whenever I tell Sophie that I love her, her normal response is "Thanks, Mama". Tonight when I told her that I loved her she said, "Thanks, Mama! I love you, too."
