Telling negative words is a hindrance to the mental growth of a child.

yep that correct. for my own opinion never say negative to a child. he/she will be confused on what are your goals for him. while your kid is still young mold them to reach the same goal you have for them . set the goal with them and talk to them like their are mature person.for example you want your daugther to be an atty. even if she dont like it . make them like it!!! make sure everyday tell them a positive view in being an atty. look for role models for them. make it everyday habit to remind her how an atty works, meet people, salary and all other things you think that will help your goal !!

You are absolute right. Words have power.

I agree with you. As a primary school teacher I can say that positive words work best with all children. I am sad when I hear a parent tell their child something like 'you are a bad boy!' The boy is not bad but maybe the thing he is doing is not awfully nice. A much better stategy would be to get him to do something else that is good, then praise him. I have heard children so disturbed that they can say 'I hate myself.' This is terrible, the parents have made the child feel so negative about themselves. It must be very upsetting for any child to hear 'you are not intelligent.' Maybe she is not very good at maths now but all she needs is some help and understanding. Saying 'I am really proud of your effort' would make most children happy. In teaching we have a saying called 'catch them being good', this is what really works. Praise has a positive effect on children. Negative words can stay with children for years and hinder their progress.
