My understanding is that as babies that their humidity and temp requirements are critical to success. Her warm side is 81-79 and her cool side is 69-72. Humidity has been steady 99% in her tub. I am changing her substrate every 2 weeks is the plan to keep mold and mildew out. She buries herself in the substrate and waits for food. I have seen her use her hot and cool side as well as water bowl. She is a little more active at night than during the day. I do want to make sure she can climb if she desires to.
