Polygamy in Nigeria Today

Whenever I read propaganda in newspapers about family planning, or see posters about it in child welfare centers, I wonder whether the propagandists come from polygamous homes. If they do, it makes me laugh. How can one explain family planning in a polygamous set-up? Who limits the number of children: the husband or the wives?
In a polygamous home each wife's importance is dependent on the number of children she has and there is competition among the women in this respect in order to get maximum benefit when the father of the house& joins his ancestors.
The trend in Nigeria today towards polygamy and to justify their actions we hear our men saying, 'The African is by nature polygamous.' This is a wrong attitude. In the past our forefathers needed a lot of children to give the prestige. Women were married humbly. But the advent of learning has changed the situation. We find that to live well in modern world we must limit the number of children in the family and this is only possible if one man decides to take only one wife.
Moreover, it is time our women started to think for themselves what they want in a marriage. Is it just a question of marrying any man, even if he already has a wife and children? Is it really fair to share a woman's husband with her? Do women really want to be regarded by men simply as a means of producing more offspring? A man with his one wife can plan the number of children they want together. I have yet to see how this can be done by a man with many wives
