Think with their mind. Do not feel shy in bringing yourself to their level. You should figure out their likes and dislikes and direct them politely.
Do not give them a lecture in front of others as it really hurt their self respect. The best time for such talks is just before they sleep. Tell them your personal experiences in the form of a story this will stick to their minds forever.
Conversely, you should encourage them and praise them in front of others. This will fill their mind with a sense of achievement and they will not feel bad if you make corrections later.
Show your confidence and make them realise that you trust them. This will help them in building self confidence and ultimately they will learn how to accept criticism. By having helpful and encouraging parents will make them feel protected in harsh times.
Do celebrate and appreciate their every success. For example, if your kid is participating in school’s sports gala and he fails to hit the mark then do not yell at him rather show him that to be in the contest is itself a victory.
Be communicative and extrovert in front of your kids. Make them realise that you love them and this will help them to handle your criticism.
If they are doing something wrong, let them face the consequences. For example, if your kid is fighting with the neighbour’s kid then do not interrupt and let your child face the music. This will teach your kid a lesson without your involvement.
Give them respect and address them courteously as recent studies show that children listen attentively if given respect.
Do not make any negative comment about their physical or mental deficiency.
