Jennie, John had his peg put in during his cancer surgery also. The peg is generally not a big deal. By the time he leaves the hospital the incision shouldn't bother him too much and will just need to be kept very clean. Getting him to use it faithfully may be a battle for you[depending on his personality] so just be firm. He will need the nutrition and hydration. I know how scared you are. The bottom line is YOU are gonna have to be strong for your whole family! It's a really big job. Let us help you through it.
