We have been made aware (by Sefton Council) of an e-safety link for parents which will help you decide whether the sites (including social media) that your children visit are safe. We are continually hearing of inappropriate sites and of children having accounts with privacy settings which are not set properly. It is run jointly by the NSPCC and O2.
It is a good source of up-to-date information.
A further source of useful information can be found at -
Links to these sites can also be found on Parents/e-safety
