I guess the best suggestion I can give is adding some form of preparation for the chaos that might ensue later. Perhaps having things such as sprinklers and auto-seed planters which could become fairly important later on. Also giving them their own issues such as the sprinkler needing to be watered multiple times, and the auto-seed planters needing to be reseeded.
However that's just off the top of my head, I'm sure by testing a few different ideas you could come up with an even better method.
Good luck! :)
