Kristen's Knees

About a month ago I took Kristen to an orthopedic specialist for her knees. She has been having chronic pain in her knees that we just can't figure out the reason why. So all that to say that the last time we were at the Dr.'s office Kristen had X-rays taken of both knees. This time when we went into the Dr.'s office she said, "Mommy today they are going to take pictures of my knees and my knees are going to say 'CHEESE'!!!".
