Okay, so this is how it's going to be for a minute. All the advise you've been given is valid, but it will help you to understand why he is doing it. He is still a baby, and his only instinct is to eat, sleep, and survive. It will be the better part of a year before he catches on that your not going to try to eat him. Just keep loving him and in about 6 months if that behavior persist get an adult bearded dragon and let them see how the adult interacts with you. (DON"T LET THEM INTERACT!) But let the baby see the adult being picked up. Let the baby see the adult be... kissed, hugged, fed, handled, bathed. Anything that you're having an issue with and the baby with mimic the behavior. But until they get out of the "everything is going to eat me" phase there isn't a whole lot you can do but wait them out. A baby beardy is one of the most frustrating and heart breaking things in the world, cause all you want to do is love them and they're like NO!"
