POSITIVE PARENTING
Dear Parents
I am forwarding you something I read and felt will be very useful to each one of us.
Give time to read it and think over it.
Tirukkural was written by Tiruvalluvar (a Tamil poet/writer) more than 5,000 yrs ago. It’s one of the ancient sciences on Human Behaviour, which has not changed in spite of modern education & technology!
SOME GOLDEN THOUGHTS OF THIRUKKURAL:
1. *If your children lie to you often, it is because you over-react too harshly to their inappropriate behaviour.*
2. *If your children are not taught to confide in you about their mistakes, you’ve lost them.*
3. *If your children had poor self-esteem, it is because you advice them more than you encourage them.*
4. *If your children do not stand up for themselves, it is because from a young age you have disciplined them regularly in public.*
5. *If your children take things that do not belong to them, it is because when you buy them things, you don’t let them chose what they want.*
6. *If your children are cowardly, it is because you help them too quickly.*
7. *If your children do not respect other people’s feelings, it is because instead of speaking, you order & command them.*
8. *If your children are too quick to anger, it is because you give too much attention to misbehaviour & you give little attention to good behaviour.*
9. *If your children are excessively jealous, it is because you congratulate them only when they successfully complete something & not when they improve at something even if they don’t successfully complete it*
10. *If your children intentionally disturb you, it is because you are not physically affectionate enough.*
11. *If your children are openly defiant, it is because you openly threaten to do something but don’t follow through.*
12. *If your child is secretive, it is because they are sure that you would blow things out of proportion.*
13. *If your children back-answer to you, it is because they watch you do it to others & think its normal behaviour.*
14. *If your children don’t listen to you but listen to others, it is because you are too quick to jump to conclusions*
15. *If your children rebel it is because they know you care more about what others think than what is right*
