I for one can surely attest to jumpy baby syndrome. Most of our hatchlings are snappy and generally super nervous when they're young. About half of them grow out of it with handling. A lot of times it's just the individual. I have some snakes that seem to really love seeing us and being around us, and others that are downright TERRIFIED every time we open a tub. Handling is the best recipe for helping the skittishness though. For like 10 minutes once a week. It's not too much stimulation, but it gets them used to your presence.
