I hear your pregnant wife...(congratulations!!) though after having actually done the laundry by hand last Sukkot, it was not nearly as difficult as I thought it would be. One of the big differences between my usual laundry method and having to do it by hand is that you really may have to do a small amount of laundry every day. I noticed that the larger families who tried to do theirs once a week had a really hard time getting it all washed and dried in a decent time. As with the composting toilet, I was actually quite pleased that the laundry was not as big of a job as I was concerned it would be.
