A good parent is invaluable to our society. Without good parents, we face a hopeless future. You know one when you meet one, because they share similar qualities, such as:
One of the chief qualities that distinguishes a good parent from a bad parent is self-sacrifice. A good parent does all that she can to meet the needs of her children, and nurturing her children is the most important thing in her life (along with the relationship with her spouse). It guides her decisions, the ways she spends money and how much or little personal time she takes for herself. Even the decision to work from home and not outside the home demonstrates a self-sacrificing attitude.
If you want to be a good parent, you must have a teachable spirit. You can't be a "know it all." That's not to say that you should follow all or even most of the advice that's freely given to you, and especially when they conflict with your values and ethics. However, if there aren't any conflicting values and if there's evidence that a practice works well in a family, then you should humbly receive and implement good advice. A bad parent shuns all advice and instruction from experienced parents, and views it all as an attack. That's the wrong approach, and you could avoid a lot of painful mistakes if you are willing to listen and be taught.
A key trait of a good parent is curiosity. There is so much to learn about basic parental duties and responsibilities that it can be overwhelming when you're raising your first child. Learning all that you can in order to do the best job possible is something that good parents do, and being curious play a big role. For example, a parent who is curious will want to investigate why some parents only feed organic foods to their children, to see what they can learn and whether that's a practice they should implement in their home. A parent, who is not curious, won't bother to do any research or ask questions. Constantly learning, keeping informed and doing your own research benefits your children and in many ways, protects them.
