Imagine discovering that your child had been sent a message by an adult, on social media or through a mobile phone app, asking whether they liked sex or what kind of underwear they were wearing. You'd probably feel a mixture of anger, panic, fear and revulsion. You'd want to take action. You might go straight to the police and tell them what had happened. But the police may not be able to do anything.
There can be few things more distressing for a parent or guardian then when their child becomes so unhappy or upset that they feel compelled to self-harm. It is therefore deeply worrying that more and more children and teenagers in this country are being hospitalised after deliberately hurting themselves.
If we're serious about improving the mental health of young people, we need a sea change in our approach to monitoring the issue. A prevalence survey once every 14 years simply isn't good enough. It's time to recognise children's mental health as a national asset, and do everything we can to understand, strengthen and protect it.
What is important is that I keep reinforcing the message that she can do anything she sets her mind to. I sent her on pack holiday with a letter telling her how brave she was and that, having faced this challenge, the next one would be that little bit easier. I also encouraged her to let her little light shine - something we have previously discussed - and told her that, as long as she did this, she would be just fine. It is a message we should be giving all children.
We know porn can be a difficult subject to talk about but young children have easy access to it - long gone are the days when this material was confined to the top-shelf of a newsagents. Children who are trying to learn about sex and relationships can access unlimited porn online, for free, 24 hours a day.
Our report released today On the Edge showed a huge increase in children getting in touch about suicidal feelings. Last year (April 2013 - March 2014) we held 34,517 counselling sessions with children who talked about having suicidal feelings - 116% more than three years ago. Nearly 6,000 of these children had told a counsellor that they had previously attempted to take their own life.
There is a sad and recurrent theme in many of the worst child abuse scandals - of a child's voice not having been heard. Poor Daniel Pelka, seen looking through bins for food at his school but whose suffering at the hands of his mother and partner was not discovered until it was tragically too late...
How about a resolution that will change other people's lives and yours too? ChildLine is urgently seeking volunteers to go into schools to talk directly with nine-11-year-old children about different forms of abuse and about staying safe. You don't need any previous experience and you will be given first class training and support.
The sharing of self-generated sexually explicit images or videos by mobile phone or online, is now commonplace amongst young people to the point that it is considered 'mundane' whether or not young people engage in it themselves. And it seems that lots do... Now, I know that young people want to experiment and explore their sexuality. And the thrill of taking risks and pushing boundaries is always going to be part of growing up. Frankly we are not going to stop sexting merely by instructing young people not to do it, or by pointing out that explicit under age images are illegal and they risk arrest. But I am deeply concerned that risks are not yet fully understood.
Imagine you were desperate to tell people about something but when you tried no sound came out. Like you'd had some awful spell cast on you that meant only you could hear the words. That's how I think it might feel to be a child who has suffered abuse but struggles to find adults who will act upon their concerns.
The Prime Minister has taken a very brave step, not just because he is taking on a problem that belongs to a multi-trillion pound industry that has changed the planet forever. But because he is saying that whilst he doesn't have every single answer to the technological problems he is not prepared to wait until he does.
