Hi purplemumma,good luck with Kane`s operation,you know they are really tough at this age and brave,stay strong for him,once all of this is over you will never look back,when you tell him all the stories when he gets older he will wonder what all the fuss was about,but we can`t help to worry,i know,our son was terminally sick for eight year(he`s in Heaven now). All the very best to you and your family Hun,
