Don't try to make your children forcefully mature. Don't teach them to behave like elders on every small thing. Don't bind your children in limitations. Nor teach them too much on each and every thing. 

 

You are not justifying with their lives by doing so because they will learn what you teach them. If you let them live freely and fly, they will learn by their own experiences.They will learn to react in complicated time and handle them.   

 

You will be responsible for their failure or mental disease if you do so. They will remain emotionally cling to you even in their young age and may be monetarily too. Moreover your children will behave with you in the same manner as you did when they grew up. Don't say or treat them like a fool. They will  become fool in reality. 

 

You can make your children what you long to be. If parents treat them like champions they become. If like God's App they become. Don't show your knowledge of maturity in everything. 

 

Let them enjoy and learn by their goofy activities. The excessive maturity is always harmful. They will forget to enjoy small actions which are necesary for their long life. Their is a saying in sanskrit too "Ati sarvatra Varjyet" means excess of everything is harmful.
