I worry about that too. And you have a baby...my little Russian is at least 17 years old but I don't have an underground hide for him. So if he's hiding in his hut too long I bring him indoors. You might not have that option. I do have that option only because I'm "considered" elderly and re tired...It's funny, I want it to be sunny for the torts but I don't like it when it's too warm. I wonder what temperature it needs to be for a tort to go " Nah this is too hot for me mate"
