They sleep...

Right now I am sitting on the floor under the couch where my toddler is past out to Monsters Inc. after a morning full of vomit...with a baby past out in my arms after nursing. My hair is still a mess, I'm still in my pajamas, Saturday plans have been canceled...and I am overwhelmed with a sense of joy...how could I be this lucky? What is it about sleeping babes that turns any situation into the best moment of your life?
