It would be in my opinion, having three now grown men....Greatly significant.
Esp if you have all boys, the father will need to be a role model.
If all girls, the mother can be a great role model.
The parents are 'the' most watched as they are growing up, they are their center of learning.
At about 9-10 children will also follow their friends at school, so one has to have guidelines for the children,so they do not have outside influences, that cause problems in the home.
Having said that, the child must also not be discouraged in finding out 'who' they are, in this world.
Balance in all we do as parents,is the best way to bring up a child.
Where your parents failed, you correct that...where they did well you use that.
At the end of any day, your children must be given a lot of love and kindness.
