Rebelious teenagers

I think grandparents are in a unique position to offer a special kind of love to troubled kids.  I wish you every blessing as you love your granddaughter.

You are so very very right!
No matter how horrid they can be, loving them through it all, and guiding them, and leading them with your more adult behaviour is the best way to go. Of course they need rules and expectations, and discipline when required, but they are learning to become adults, and we as parents (grandparents, guardians), must take that role seriously. When teenagers are met with negativity, hate and violence, that is what they learn. When they are met with love, guidance and understanding, that is what they will eventually bring to the world, once they pass through that emotional, hormonal chasm that is teenagehood!
