Women have taken a role in raising children in most societies for hundreds years. They have the greater role at parenting than their spouses. It is because that men have taken a role in supporting their whole family, not just for their children. It is common in most societies and has not been changing so far.
There are several reasons that women have the greater role than men in raising their children. One of the main reasons is that men work for their family and spend a lot of times outside. Therefore, women inevitably spend much more time with their children than their husbands. Women do many things for them such as cooking, cleaning, upbringing and much more. In addition, men need to take a rest after their work for next days. Therefore, they become neglect to take care of their children.
However, some people claim that men are as good as women at parenting. Moreover, they also insist that men would take the parenting role instead of their wives. I strongly believe this claim if the roles of each others are switched. For example, men do the domestic works for their familiy and women work for their family. Indeed, many parents that wife has more ability to earn more money than her husband are encouraged to exchange their roles if that is the better way for their families. These cases of husbands are also good at domestic jobs.
To summarize, men are as good as women at parenting if they are good at domestic works and their wives have abilities to earn money enough as well.
