maybe create night and day, some villagers sleep at night the majority of them and work during the day others like to work at night and sleep during the day.

maybe when a female gets pregant to show her with a big belly and have another women go into the hut to obe a midwife.

show the villagers as tired so you know when to let them go to sleep?

maybe its just a suggestion
