Just going back to the food thing... She looks a little thin to me. She probably is hungry. She can eat a prey item as large as her widest part. I would up the feeding. Guessing her size, I would say she could handle more than one mouse per feeding, or a appropriate sized rat. You can also feed her every 5 days.
As far as shedding, they get "blue" then a few days after the blue clears up, they will shed. Make sure her humidity is up so she has a good shed.
What is that substrate?
Congrats on the new baby!
