First off, if she has decent size right now, she could easily go weeks, even months without eating at all. Of course not recommended, just letting you know so you don't stress out.
For a newly arrived hatchling I always wait several days before offering food. New enclosure, shipping or even just transporting can be very stressful for a baby. Let her settle into her new surroundings. I saw you waited four days that's good. Also sounds like you've tried multiple times since then? I only offer food once a week, eat or not. Best response is in the evening. And go small to start with, maybe that first meal was too much?
Of course check and verify temps and humidity right away!!
are you feeding fresh killed (F/K) or frozen thawed (F/T)? Often babies won't eat F/T right away but will readily take F/K.
