Try moving the UTH to under the tank instead of the side. You can't get an accurate reading this way for a snake who needs belly heat. It could be warming up the air but not the belly. Make sure you are using a thermostat or dimmer. Set it for no higher than 88 F. Some owners do well at 90 F and I had that with my bp at the start when he was tiny. He was avoiding his hot spot and many suggested to lower the temp to 88 which worked for me.
Using a hair dryer after thawing the rodent helps greatly. The food must be as warm as it is alive, and live rodents are quite warm. Not only that, if you dry it near the tank, the smell would usually get her going and ready to eat.
I believe the lowest temp you should have is 80 F. I don't know if being 2 degrees would make a big difference so someone else can confirm that.
Hides should touch the sides and top of the snake. The more secure it feels, the easier it can settle down. You can pick up a plastic plant dish for less than a dollar at your local hardware store. Cut a hole and you are ready to go. Always use identical hides.
No handling until she eats consistently for several meals. Some suggest 2-3 (which is what I do with all my new snakes), others recommend at least 4-5 depending on how shy your bp is (Some are naturally more easily spooked than others).
Add more clutter in your tank. This cam be done with fake plants or newspaper. You can pick up a sizeable fake plant from your local dollar store. Less open space = more security for the baby noodle.
Lastly, once the husbandry is fixed and she starts to eat again, she needs to upgrade to a small mouse or rat pinkie. There is a feeding chart in the forums for your reference. I would stay with mice until she eats more consistently, gain some weight, then prepare for the switch to rats starting with rat fuzzies (when she is ready for another upgrade to medium/adult mice). Hoppers are too small for her at this point but since she refused her last meal, I would fix the husbandry, try again with the hopper, if she eats it, upgrade to small mice next time.
