First camping trip with a toddler - any survival tips?

ngl I'm nervous about this. We're planning a 2-night trip in May with our 3yo (first time camping) and our 7yo. I'm worried about sleep schedules getting wrecked, diaper changes in a tent, and the general chaos. Anyone done this before? Do we need a fancy camping setup or is a regular tent fine? How do you keep a toddler entertained at a campsite without screens?
