i just recently got a bearded dragon and ever since the first week of owning it it tries to bite! im not mean to it and try not to handle her to much just to bath her and hold her once and a while. but every time i reach in to pick her up she puffs her beard and opens her mouth like she wants to bite me. she hasn't really yet but im confused is that normal for babies or does mine just hate me?

i have had a baby before and he was always a sweet heart but i think thatz cuz he was in a pet store and saw lotz of people all the time. If n e one knows n e thing please inform me.
thankx
