Depends on the temperament of the little hatchling and how it was raised prior to your buying it.
Peppa has always been really into being handled, she really loves a nice snuggle and being petted, has from the get go , she is also a very pretty little dragon and I believe the breeder was very fond of her and handled her very frequently (I suspect she was thinking of keeping her for herself as a hold back)
Her brother Toothless was and is completely different, very highly sprung and while being extremely inquisitive about us and everything was very skittish and standoffish when it came to being handled so we kept the handling to a minimum , essentially only initially taking him out of his tank once a day to bond by offering him a few crickets by hand....and taking the opportunity to pet him while he was munching. He's still quite a livewire and not so keen on being picked up , but once on the chest or tummy he calms down for a while and "tolerates" some petting and a snuggle until something grabs his attention then he's apt to want to go and take a look.
Generally , if they are enjoying the experience their breathing will slow down and they'll colour up nicely and brightly in the sides of the face.
My advice is play it by ear , and if you think the little dragon is not really enjoying the experience back off and let it get more used to you and learn to trust you.
