I donno but did you try and leave the pinky in her hide where she is? Also try and not provide her with any daytime lights. Keep temps at normal degree, and cover tank with towel for a couple of days. I would leave the pinky in her hide for about a day an a couple of hours.

Also when she start feeding again, try and get her a new enclosure. Try a 12qt Tub heated with flexwatt. Tubs are great for Bps, they hold humidity and provide the snake with plenty of cover from the plastic blurry walls. The tub is small and the Baby will feel safe in a tight space as a 12qt. As it grows and starts feeding on small mice I suggest switching her back to the 10 gallon.

IF THIS DOESNT WORK CONTINUE ON WITH THE TUBE FEEDING, THAT'LL BE YOUR ONLY CHANCE. WHAT YOUR GOING THROUGH IS COMPLETLY NORMAL. BABIES ARE STUBBORN AND SKINNY AND WE TEND TO WORRY DUE TO THERE SIZE. I KNOW SHE'LL BE FINE. GOODLUCK
