It is also good to remember that, especially with juveniles, a hand that moves in unseen from above or behind will cause an instictive reaction from the gecko such as jumping and/or barking.
I have a gecko just under two months old which comes out of hiding when she hears her enclosure open and steps into my hand voluntarily looking for food. IMO, 2 months is not too young as long as you are aware they may jump, and you keep them no more than several inches from a suitable surface like soft carpet, a couch, or a bed. The fact that you have only had her 5 days, and trying to handle or is more of an issue in my opinion. It usually takes close to two weeks and sometimes more for the stress of a new environment to wear off, but I'm pretty sure we already covered that in another post.
