I believe the issue of "what is the appropriate age to have children" should depend upon the individuals involved and whether the choice has been given adequate consideration. For example, I know of a very young couple having a child and they are very mentally mature and responsible -- more so than many older people that I know. I have little doubt that the values they live by will do them well. They have gone back to school to further their education. No doubt they have more burdens to juggle than the average student. At the same time though, they are much more serious at learning than many of the other students in their class. While that may not be the typical case (I don't have statistics at hand to know), my point is just that it is really hard to judge what is ideal without knowing the individuals and circumstances involved. Some people thrive when added responsibilities are thrust upon them. I don't see a problem as long as people think ahead, with good information, when they are making these choices.
