No, the point is that there is more to life than money. Caring for your own child has value that isn't captured by the amount of money you would have to pay someone else to do it. If you only care about economic efficiency then the whole idea of childcare is misguided; to maximise productivity you should set children to work as soon as they're able. FYI, "comparative advantage" has a specific meaning, it isn't just a synonym for "advantage, but in economics".
