Early to bed, early to rise seemed to be the motto among the Amish. Nine o'clock was considered to be late.
Even with getting plenty of sleep there was something about the long church services that seemed to put people to sleep. Usually when the second minister started preaching the boys would settle in to get as comfortable as possible to sleep. Married men might try to stay awake, but many of them dozed off.
Women weren't immune to sleeping in church either, but with have babies and little children to care for it didn't happen as often.
