As above post says, see the guide linked to.
Baby BPs are not started on "pinkies" (mouse or rat) because pinks of either species is too small. You want to offer at least a fuzzy, & if she was only fed live (not already switched to f/t?) then you'll have to be patient (& hopefully transition her to f/t in time...for now feed live if need be). Hope she came with a feeding record? Also important: offering food too often (more than every 5-7 days) just stresses a snake more, so don't do that, ok? Be patient...
Have you been handling her? You've only had her for 2 weeks & all snakes need time to settle into new homes...that means no handling at all until they have fed at least 3 times (establishing that they are settled in), & it's best not to feed (offer food to) a new snake for at least the first week anyway...it's often a waste, as they just aren't ready.
Snakes are basically wild animals...they rely on their instincts to survive, & guess what? the only thing that picks them up in the wild is a predator about to eat them.So handling is best postponed while baby snakes learn to be snakes first...handling (& their resulting fear) tends to turn off their appetite. You'll have better luck if you're patient with all snakes...they do learn, but gradually. Eating is job #1.
Feeling secure is a big issue for a snake to accept food. How you set up their cage matters...their snug hiding places @ the right temperatures matter...and NOT being under bright lights matter. Ambient room light is fine...usually lights are used only to add warmth in winter...best if not the only source of heat, since heat rises and most heat from a light doesn't not reach the cage floor where the snake is needing warmth to digest. Be sure that all heat sources (including light if used) is regulated for safety.
