I am sad for the number of stories I hear of teens being "typical teenagers" moody, withdrawn, hostile, etc.
I don't think this is typical teenager at all, but I do think a lot of parent child relationships break down badly in teen years and the seeds for that are sown many years earlier.
Some examples recently - asking a mum how often she tells her 16 year old that she love him - not in the last 10 years she says - ie not since before he was 6! So she says she can't start now, it would be weird. But it need not have been weird if he had grown up with it being normal.
Arguing about who gets teens over Easter and who gets the weekend "off" - why are parents saying this? Children hear and know - why not argue about who gets the privilege of weekend with the children?
Horrible things said, like menace to society, and waste of space, etc.
Please have conversations with your teens every day and tell them you love them. Please start when they are tiny and it will often just carry on naturally
