1. If circumstances do not allow you to help people , just make sure you don't harm them. Jesus Christ did not blame the 5 wise virgins for not rendering self-harming help to the foolish virgins (Matthew 25: 1-12).
2. There is a limit to human help (2 Kings 6:26-27 ; Psalm 49:7-9) . Even the biological parents of an only child will not be able to help him rear up his 4 children, 16 grandchildren, 64 great-grandchildren, etc.
3. Don't distract people from facing their own battles. Neither try to profiteer from other people's problems. Don't dump your children's upkeep on someone who is childless or has lost a child. They will see you as the architect of their problems. Nowadays, most childless women battle fibroids, etc and can't afford to shoulder the upkeep of other people's children as well.
4. Don't have more children than you can handle alone (in case of divorce or widowhood , and even to enjoy your marriage ) . Even God directly created only 2 people (and left the remaining production to us, via reproduction). Having many children even increases a woman's risk of developing placenta previa, cervical cancer, etc. There is a medium in all things.
5. Extensive farming (along with attending public schools) can help large families to survive. Labour is a factor of production. That's how our forefathers survived in the olden days.
6. Yorùbá people say :(a)"Òrìṣà jẹ́ n pé méjì obìnrin kò dénú"( Deep down, no woman wants her husband to have another wife) ; (b) "Ẹní bímọ fún'ni kúrò l'álè ẹni" (the mother of your child is more than a side chick or mistress). Therefore, don't let any woman see (or know) you as her rival, or your child as her stepchild. That's how not to be a home-breaker.
7. No cheating husband can commit maternity fraud against a woman. A woman can always tell her own child apart from a stepchild. That is nature's compensation for the labour pains. Remember this biological advantage when tempted to cheat back or fight other women over a man.
May God bless all our well-wishers and make the plans of the wicked against us backfire on them. Amen.
