There is no real definition to being a good mother, but I did find a link that covers the area of what being a mother is in modern times. https://revolutionfromhome.com/2018/01/modern-day-motherhood-feels-frustrating/
Apart from that, for both men and women, I believe that it differs. For example my parents are old school. They have an older thinking about what roles they have as parents and what they should be doing gender wise.
Being a good mother can be very taxing on the body and mind. I think that for women now, they will have to deal with what society expects out of them more because of social media outlets pressing on the issues of how good other celebrity parents are or are not.
For men, I think it’ll be hard for them to accept the fact that being a good mother is a lot of work. That being said, men will have to understand that not all hard working mothers are as free as they might think. Although now, it can be said that men are contributing more and more to the aspects of motherhood because they understand the hardships.
Even though there are still a lot of things that can be said about motherhood, what I can see is that both men and women have to contribute their time and energy to have a healthy relationship. Motherhood is very taxing all on it’s own already, so with enough support, it can lighten the load.
