baby bearded dragon behavior

Question
I have this baby bearded dragon that i got 1 month ago. Every thing was fine i held him and fed him daily. A few days a go i took him out and he stated to his at me and open his mouth so i put him. When I tried to take him out another time he went to bite me, it wasn't bad because hes young but I'm afraid that he might do it again when he gets older. He started to shed for his first time hes bin with me so i don't know if hes submitting aggressive behavior because of shedding or of me not holding him for a few days. Please tell me what's happening to my bearded?

Answer
 Shedding can make them a bit itchy and a little pissy, but insist on picking him up everyday and don't put him down till he's calm.  Mist him to help with the shed and a shallow baby warm bath will also be good.  Give him a lot of attention and always speak to him.  The more you do the more he'll bond with you.  
 Be aware that the closer he gets to you now, the less nasty he will get when he reaches 5-6 months old.  That is when the hormones kick in and he may be crabby for a few weeks.  But if he's trusting in you, he will not bite like he would as a baby.
