One of the most important advises in Islam for raising children, said in modern terms : " Lead by example ". That is , do not ever lie to your child, in any way. He will pray if he sees you pray, he will be helpful to others if he sees YOU help the others. Telling him to do a behavior and doing its opposite is a sort of lying to him.
A second one is about the stages of the child life, and how to do with him :
in his first seven years, you play with him. That means you raise him by love in his early sevens. He is still young and needs love from you, so reveal to him your kindly face : play with him, bring him toys, learn him the good behavior by kind words and tender feelings.
In his second seven years, that from 7 to 14 : discipline him. Show more strict behavior, and this of course depends on the behavior of the child.
In his third sevens, that is fro 14 to 21 : treat him as a friend. He is now growing up, he needs to feel that he is treated as a grownup by you. This boosts his self confidence and prepares him to the grownups life to come.
After that : he is now an adult, so let him live his own life, armed by what you give him in the 3 stages before.
I hope this helped.
God bless you.
