debate on topic "children are mirror image of their parents".

You haven't mentioned whether you needed pointers for or against the motion. However, here are a few for your reference:

- Kids, walking reflections of their parents

- Biologically, transfer of same genes brings out certain noticeable similarities

- Behavior pattern of a growing kid depends on that of his/her parents

- Children tend to imitate their parents in every way

- Lack of positive energy, love or warmth at home can be reflected in a child's behavior 

- Might lead to loss of individuality when a kid grows up like a parent

- However, making parents ideals is also a good trait

Hope these helped!
