Question: How old should you be to get married or have a child? 

Answer: It's not age that matters its how much they know about life and how much they can handle. If you think you're ready for marriage and kids then babysit for a weekend and have your partner help you. You can learn how each other would be with kids and responsibilities. It also has alot to do with the maturity level and maturity only comes with time and lifes experiences.
