Camp, babies are a bit more nervous and apt to nip than a lot of adults. Remember this is just a tiny thing, without a clue you are caring for it's wellbeing. It's just a little and lovely creature that has a lot of survival instincts driving it so they may well nip or jab (closed mouth sort of thing) at you right now. Lots of babies hiss or watch intently. They want to make sure you aren't a big predator about to chow down on them. Remember they have very few ways to deal with you...bite, jab, hiss, escape, ball up or hide...that's about it.
Seems every young snake we've had that was a bit on the nippy/hissy side ended up being a really great feeder with fantastic hunting skills so I consider it a good thing really. Eventually as they mature and you do some simple routines with them over and over again, most will calm down nicely. We have a couple that still hiss at us every time we touch them but funny enough, those are the two that have never attempted to bite...they all all hiss and not much else. LOL
