So, ideally you'd want to run the loads on different circuits. So, ventilation on one, lights on another, pumps/water things on another (preferably GFCI protected). That's in an ideal world.
Some of the resident sparkies can speak more intelligently about this than I can.
What i would do is see about getting a hold some of those surge strips that have super long cords. You want at least 12 AWG just to be sure the load doesn't burn up the extension cord itself. Then, you can run one off a timer for your lights. Run your other equipment off the other one, but have that second one on a different circuit. So, like, your lights are on the living room circuit (outlet behind a couch or whatever) and the other is ran from a bathroom outlet. That'll distribute the load more even across your panel and reduce risk of overloading an outlet or breaker quite a bit.
Hanging the cords will be another challenge in of itself, and you'll have to get creative in whatever ways you can. It's also a great opportunity to start teaching her about the dangers of certain things. So, like with our kids, we'd point at a dangerous object and say "OWWWW no touch." So like, stoves, pans, knives, electrical things (lights, plugs, heaters), etc all got the "OWWWW no touch" treatment. It helped avoid a lot of the more potentially serious injuries, but they'll still get curious at some point about some things.
