One of the problems
with polygamy is that these
families usually have many children. There
may be 20 or more.
In African society,
according to tribe, the father may
not involve himself very much with his young children, much less if there are many children.
If a father waits
until his child is in the early teens, it will probably be too late to bond with that child.
Being one person, it
is difficult to love a large number
of children well.
As James Dobson has
noted, children need to know that
you are on their team, that you
are on their side and are cheering for them to win. Then when you correct them, they will know that you love them, even if they think your correction is misplaced.
