Leopard geckos don't need to be handled, actually. No reptile "needs" to be, they don't crave affection like cats or dogs. Leopard geckos are usually calm enough that you
can handle them but never feel like you have to

. There's a really common misconception that not handling leopard geckos enough can make them less docile but I haven't found that to be the case. Even if I go months without handling a reptile, they're always just as calm/not calm as they are when I handle them more often. So it's up to you how often you want to take her out.
That being said, it's usually recommended that you leave a new reptile alone for a while (I would say a week MINIMUM, two weeks would be better) so that they can acclimate to their new home. Handling a new reptile can stress them out. Also, always make sure the reptile has been proven clean of parasites from the vet, is eating, and seems generally healthy before handling.
