Scaredy beardie

I have a baby bearded dragon that I bought at a reptile rally in the middle of October named Arlo. He is literally scared of everything. I get him out every day from the time I get home from work until the time we go to bed and hold him, let him explore his territory a little bit, but he is super clingy and wants to crawl up into my hair and hide. Is this something that generally goes away with time. He is between 5 and 6 months old and was only as big as my pinky finger when I got him and barely six weeks old, so at first I thought it was because he was so small but now he is 16 inches from head to tail (huge for his age) and he doesnt seem to be getting much calmer. I'm beginning to think it is just his temperament because this is not my first bearded dragon, he is just the first baby that I have raised from such a young age. Is this something I should be worried about or will he grow out of it in time??

I am sure he will grow out of it somewhat in time - and it could be his temperament- its hard to say - they tend to mellow out more as they get older - Hiccup was some what the same way when we got him as well but in time hes 2 now hes mellowed out but he still scares easily - thats just him --
