Does she have a hide? I just dealt with this and read a bunch. Take her out of her enclosure and clean her whole tank down. Pythons don't eat sometimes when they can smell themselves due to in their mind their prey can smell it too. Make her a new hide. Clean cage. Take the ft and put it in the cage right outside of her new hide. Put your baby in the cage with the mice in it already. Then throw a dark blanket or sheet over her whole enclosure. Let her be for a few hours. If she doesn't eat. Wait a day. Take her out for a half hour or so and let her relax. Put a new mouse in and throw her back in the cage. I know people say handling them before feeding is bad. But my snakes love to move around and once they get their blood flowing I put them in and they are ready to eat. Just my thoughts I'm no expert.
