The Amish seem to be known for how much they help each other. It's true they do help each other when there is a need, but it isn't every day, or every week. In fact, months can pass without the community coming together to help someone.
Gardening, canning, quilting, and almost everything is done alone with only the members of that particular household.
Hired help on the other hand is a lot more common. After a baby is born a girl will usually be hired for the next six weeks to take care of all the household duties and any other children in the family while the mother gets to relax and enjoy her new baby.
Farmers that don't have any children old enough to help with hay making and some other tasks around the farm will often hire young boys to help out.
