For me, it mostly centers around the heat factor.
I make sure they've gotten "warmed up" before feeding, about 1.5 hrs.
And then that they have plenty of heat after eating, about 2 hours.
Same rules with
bathing in my house.
I also don't take them out for more than 6 hours at a time. Granted, that one's very rarely an issue!
A lot of times we encourage people to have a flexible schedule for their beardies. Like, have a schedule but take them out at different times. The goal is give them consistency, but don't make them too routine dependent.
