I think the bite also indicates that Wiggles has settled in and he's more comfortable with his new environment. His previous owner warned me that he sometimes mistakes fingers for food. Until now though, I haven't seen that. Generally, I haven't seen the food aggression for which Children's Pythons are famous. So, I'll take the bite as a positive sign that Wiggles feels safe and secure enough to let his personality show.
What it tells me is that he needs more "socialization". He knows how to be a snake, but not how to be your pet. He can do both, trust me.
