Just looking for some advice for my 9 year old step-daughter, her mother has gone behind my partners back and given her a phone with access to the internet (unrestricted and we have found out she has social media now aswell) my partner feels she is far too young to have a phone and to be on any social media and has no need for one as she is still in primary school. None of her friends have one either. My daughter is the same age and my son is 7. I am quite strict when it comes to the internet/social media, they have tablets that have restrictions on and both know that they can't have social media until I deem it appropriate. My step daughter recently sent my partner a video of swearing and a few other things that a 9 year old should not be watching or repeating. We spoke to the mother who said it's none of our business what she does on her phone. The 9 year old is also talking to strangers and seems to be left to her own devices. The mother just doesn't seem to care and we wondered if there was anything we could do without upsetting anyone. when she's with us she knows to follow our rules but reminds us she can do what she likes at her mums and she doesn't have to listen, she gets told that when she's here she's treated the same as everyone and respects our rules but this falls on deaf ears most of the time and it's becoming difficult because my 9year old is starting to pick up on it. We are trying to be consistent with her but it proves difficult when it's constantly on sided.
