Safe sex chat
Some people may think that images and videos only last a few seconds on social media and then they're deleted, but they can still be saved or copied by others.
This means that photos or videos which a young person may have shared privately could still be end up being shared between adults they don't know.
It's easy to send a photo or message but the sender has no control about how it's passed on.
When images are stored or shared online they become public.
So it's not surprising that sometimes children's sexual development can seem out of step with their age.
Alternatively you can make a report direct to the Internet Watch Foundation (IWF) on their behalf.It may feel awkward, but it's important to explain to children the risks of sexting, how to stay safe and remind them that they can talk to you if something ever makes them feel scared or uncomfortable.Sexting is when someone shares sexual, naked or semi-naked images or videos of themselves or others, or sends sexually explicit messages.Remember you can contact the NSPCC helpline 24 hours a day to speak with a counsellor if you're worried about a child or need further advice on keeping children safe.CEOP’s Thinkuknow give advice for parents, as well as children and young people of different ages, on staying safe online.
