Biology Meets LIfe

So we all know how to make a baby -- it's pretty much all taught in fifth grade health class and every year after that until end of high school. When I got married, everyone told me it takes about a year to get pregnant so plan early. Obviously, it didn't take that long for us. We were experts at it from the getko. People that didn't know us from before have asked me how long did it take us. I always find it strange - I just figure you figure out when you ovulate and then just have a lot of intercourse around then if you are not certain exact day. Obviously, we did not take that approach since we figure it would be hard and we had time to wait.

Anyhow so the biology part seems very simple, but why is it so hard to raise a baby? It seems to me that they should just have the same manuel for taking care of one. I have read a lot of baby books from baby "experts." It just seems like these experts can't figure out why Mattie doesn't sleep through the night, not eat meals properly, and why does he just cry for everything. It seems like, nature should only allow people who knows how to be Mommies and Daddies to procreate.
