Be a Super Hero
As mentioned above, it is important that you act like a super hero around your child. I do not mean that you need to go out at night in a mask and cape and go out and fight armed criminals. I mean that you need to always do the right thing in every situation, no matter how difficult it may be or what rewards a negative decision may offer you. By doing this you will show your child that it is important to always do the right thing.
It is important that you lead by example. It is much more likely that your child will pick up on the lessons being provided when they are by example and not just from things that you say. This is especially true when parents try to tell their children not to do something because it is bad. You must understand that it is difficult for a child to wrap their mind around this concept. For example, many parents tell their children not to smoke cigarettes because they are unhealthy and can kill you, while the entire time they have a lit cigarette hanging out of their mouth, This message will surely not be retained as the child will think nothing of it after watching their parents do exactly what they were telling them not to. The same goes for teaching your child morals; you must practice what you preach!
You need to determine what morals you need to teach your child and find ways that you can demonstrate these morals by example. For example, if you want your child to learn to be kind, you may help an elder neighbor carry in their groceries or help them trim their lawn at no charge. Another way you can show this moral value is to give to a charity or provide a meal to someone in need. If you want to teach your child about being accountable it is important that you take responsibility for everything that is your fault, no matter how small you may think the issue is or how bad the outcome may be. This will teach your child to not fear the consequences of being honest and to be more accountable for their decisions in life. If you want your child to learn responsibility you may want to try taking them to work with you for a day so they can see all the responsibilities that you have on daily basis. You may also want to have a talk with them about the responsibilities in life of paying the bills and making sure that there is always food on the table. This will help them understand that life is not one big game and will prepare them for the day that they must become responsible for their own life.
Basically, what you need to do is determine which moral values your child may be lacking or which morals you would like to change about your child and create a game plan. Your efforts may not work and first and may take some time to show progress but you will surely be successful in your efforts if you try hard enough. One of the most important things you need to do is analyze your own morals and values and make sure you are exhibiting positive lessons as a parent.
