As a mother I can tell you there is nothing in the wold as painful as seeing your child sick and not being able to do a thing about it. All I can say is be strong for Luke (I know it sounds easy to say to someone but it's true) and just believe in the BIG GUY up there. Lean on your husband when you need to and talk talk talk to others as much as you need to help get through this. Keeping friends and family close and talking is a HUGE help. Just let Luke know that you are there and love him. He will be home soon and grow up to be a strong healthy boy. You are in all of our thoughts and prayers.
