that's awesome, congrats!

She got into her water bowl and there is water soaking almost all of her substrate, should I leave it or change it? Maybe just lay some more over the wet parts?

your substrate looks to be paper towel. i would change it as it would be a quick clean-up and wet substrate can cause irritation or throw off your temps esp. with substrate that doesn't dry quickly.

And do you guys think she is too young to have aspen bedding?

she's a year old, she will be fine. also plenty of peeps including breeders keep their hatchlings on aspen or other wood substrate. as long as you can hold your humidity and temps, substrate is a matter of preference.
