My son is now five years old, I had and still have the same worries as you do. Denver will be okay as long as he is on diet. As he gets older it will be easier for you. Just remember that his levels have to be elevated for a long period of time before it does any damage to him. If you take weekly test than you will know. Also something I have noticed with my son his moods change if his levels are higher. When he was born he was very cranky baby and then after his levels came down he was fine. It will be easier as he gets older. He will be fine.
