Raising kids is not easy. If a parent has a girl and a boy, s/he might compare them in the way the two genders behave. Generally, boys need a lot of activities to release their energy as their testosterone dictates. This is not the same with the girls. Thanks to Steve Biddulph for his book, "Raising Boys" which made me understand the difference between boys and girls. In this book, he explains that boys are so loaded with testosterone that controls the way they behave. The girls are not that's why they are easier to manage and less aggressive and impulsive.
Biddulph explains that boys who cannot release their testosterone in a healthy way have the tendency to do adverse things like smoking, turning to drugs, having sex with a girl, masturbation or any unwholesome activities. Fearing this could happen to my own boys prompted me to give my boys more activities to do in order to release their testosterone aside from making them healthy and productive. So, I don't mind buying what my early teen boy asks me to buy to get him occupied such as turtles for aquarium and maintenance thereafter, table tennis rackets, balls and the table itself, tennis racket, football, badminton, basketball even piano and violin just to make him use his time and energy wisely. And, oh, my little boy has different needs to release his energy - toy cars and any machine that he can manipulate. So, my toddler is showing a high level of testosterone as well that calls for more attention from us, parents. This means that we have to take heed of this need for them to release in a healthful and wholesome way their testosterone without any bad effects until they are grown up when they are in full control of their behavior.
If Biddulph's book is taught in school before, educators like me can be more understanding such needs of boys to release their energy as dictated by this hormone called testosterone. How I wish this is included in the curriculum of every university or college offering education so teachers will be aware of it. Parents should also read this book so that they will know how to address the differing needs between boys and girls.
