Day of rest. Went to church. The sacrament meeting talks were on missionary work. One of the speakers was raised in the family of 9 children and he was the youngest. He had served a mission in Chile. Sarah and Matthew stayed home, the other children came with me. They behaved perfectly - I did not have to do anything to keep them quiet. Joseph and Jacob without any promptings opened the hymn books, found the hymns and were singing them. Afterwards a sister in our ward asked about the secret of getting them to behave. My immediate answer was home school and daily scripture study. To this I would add a general approach that removes bad influences from the home - no video games, no mainstream TV, no "not that bad" much less just plain bad movies, no music of the telestial kingdom,. no other forms of dumb entertainment. On the "do" side, in addition to regular scripture study and prayer, plenty of academic instruction, rigorous physical activity (running), and chess.
Later I wondered about our culture where it is OK to say that N kids (with N >=5) is too many, but it is not OK to say that M kids ( M <= 2) is too few. If N is too many, which one of them do you send back?
Sarah often comes home from a shopping trip and says how she does not like it when people tell her that her hands are full. I suggested she should answer - yours are empty, why don't you come and help me?
