I agree with all the people above. If a baby ball python won’t take f/t, do live a few times just to ensure they are still maintaining their weight. When she grows a few weeks older, she’ll most likely become less picky about food. I had a ball python the same age and couldn’t get her to feed for 5 ish weeks, and I was worried to death as well but once I offered live instead of f/t, she took it after 2 hours of leaving it in the tank (it was a pinky rodent and was being monitored). Try to first get her feeding, then switch her over once you feel she is ready.
Good luck!!
