In another thread, two separate points were made by separate people. One person mentioned (I'm totally paraphrasing here) that it doesn't seem like a few hours a day before and after work would be enough time devoted to spending with your child. Another person mentioned (paraphrasing again) that having lots of children would also prevent the mother from devoting more than a few hours per day per child, if not even less than the working mom.
At first I was thinking that, well, the mother of lots of kids who is with them all the time is *simultaneously* spending time with each of the children. But then again, at what point do we distinguish between "time devoted to child" and "time spent in presence of child"? Assuming that both are caring, responsive mothers, do you feel that someone who SAH with tons of children is likely to be devoting more, equal, or less time to each child than someone who works full-time and has one child?
