In my experience the handling for an hour a day will have the opposite effect. Some are just defensive no matter what until they get some size and confidence built up. Handling more may just stress them. Is it eating regularly? That'll be a big indicator if you're now over handling. I never hold any of my snakes for an hour a day. I have plenty of babies that I never handle beyond moving for a few seconds to clean tubs and to quick health checks/weights and they are equally laid back as handled ones. Just give it time and space and after a couple hundred grams it will be more forgiving.
