How's your humidity? Any recent stuck shed on her? My hotspot is anywhere from 85-88 (from a heat lamp), but she only uses it when digesting, otherwise she stays to the back of her perch where the temps are closer to 79-82. The floor of my cage can get as low as 76, but that's because of all the moist substrate, and she very rarely completely leaves her perch.
You said a baby, what's your set up? That might have something to do with it.
