i know the feeling, i'd had my very first ball python a whole 4 days before i tried feeding her frozen (and i've still had her for less then 2 weeks, nice to see i'm not the only newbie), and she caught on really quickly, despite apparently having been fed live. she was a little bit scared of me trying to wiggle it, and had to bump into it before she chomped, but i was glad she sorted it out so fast. it's a good feeling, i was super worried that she wouldn't eat!
grats on getting yours fed!!
