Keep your kids safe online

Most UK schools are now on their summer holidays, meaning that millions of children will have hours of extra free time to spend on social media - such as Facebook, Twitter and Instagram.

But do we really know what they're getting up to online and how safe they are? We commissioned a poll for under-16s, hosted by Netmums, to see how well they understand staying safe online.

Today, Mark Williams Thomas talks us through the results, plus looks at some of the most popular apps that children use, and helps parents to manage their children's online activity.

Sex change family

Aged just 15, Lleahan found out her father's secret. He wanted to be a woman.

Lleahan spent three years helping him prepare to change from Stephen to Helen and both were over the moon that Helen no longer had to live a lie.

It was at this point that Lleahan was hit with another astounding revelation. Her fiancé Christopher confessed that he too wanted to live as a woman, called ChiChi. Helen and ChiChi are both now preparing for gender reassignment surgery and Lleahan is fully supportive of them both.
