Firstly, not everything that you read is the absolute be-all-and-end-all. If you had any practical experience, which, quite obviously you DO NOT, you would be able to take the pertinent info from what you read and apply it. This is not the case with you. NO SPEAK, LISTEN!! For a LONG time, unitl you have EXPERIENCE. PLeas edo not regurgitate information which is incorrect to newbies who are taking your word as true, god forbid!!
Now, to answer your question, which I do not believe has been answered yet; Approx. two weeks after giving birth, your hatchling will shed. She should accept food shortly after that. Don't sweat it if she does not. BP are very resilient, not as resilient as an adult mind you, but tough enough. If she hasn't eaten for you a month after her shed, you may have to assist-feed. NOT FORCE-FEED. If you do not know th edifference, DO NOT LISTEN TO KNOTT!!! assist-feed is to place the dead food item gently in the mouth of the ball, and close their mouth over the head of the rat, then place them down, and HOPEFULLY, her instinct will take over and gone. Force-feeding is to actually push the food item down the throat of the snake. However, both of these can be very stressful, so only use as a last resort. Hope that helped. P.S. this is from experience, not regurgitated from a book.
