A whopping 90 per cent of parents believe social media is making their children grow up too fast, a recent survey has revealed.
Nearly eight in ten parents (78 per cent) have said they are shocked by the kinds of things their six- to 16-year-old children say - including inappropriate language.
A further 57 per cent say they are concerned about what they see on social media.
But the survey, by distinctivechesterfields.com, revealed that despite concerns, less than a third of parents keep tabs on the television their children watch, and just under half monitor video gaming.
It found that 59 per cent of parents would let their child watch an 18-rated film before they come of age, with 14 per cent letting their child view such films before the age of 15.
And just over a third (37 per cent) of parents say they access their children's taste in today's music - much of which is sexually explicit.
Tom Madders, Campaigns and Communications Director at children's charity YoungMinds, said: "Social media is part of everyday life for most young people - from making plans with friends to reading the news or scrolling through Twitter or Instagram.
"Parents can adjust the safety settings on their Internet browsers and devices, but it is impossible to monitor or control everything your child sees online.
This is why it is so important for parents to talk to their children about what they may be seeing online and encourage them to open up if something is troubling them."
The poll suggests parents in Worcester are the most relaxed in the UK, letting their children stay up latest and having the least stringent controls on TV and social media.
Meanwhile, parents in Aberdeen hold the tightest reins.
