Telling your kids
I have two daughters age 23 and 19. I had a really big problem figuring out how to tell them that I was having the surgery. I approached the subject from a health standpoint and told them that I am not doing this for vanity. I am doing this for health reasons. They have watched me struggle with my weight for many years and they both understand. My older daughter is a bit freaked out that something will happen to me but I keep telling them that I am in good hands. Tonight the three of us went out for dinner and I told them that I would prefer that they do their normal routine the day of my surgery. I don't want them sitting in a waiting room worrying about me. I basically told them that the first day I would be kind of out of it and that they need to attend classes and go to work.
I don't think it matters what age your children are, it is difficult telling them about the surgery. I find that honesty is the best policy as long as it is at a level they will understand. When the time comes for you to tell them I am sure you will find the right words to express to them what you will be going through.
