This question touches on important aspects of dialogue, boundaries and developing a capability for healthy parental involvement in their children's lives. What's most important is to find an opportunity and have an open and honest conversation between all household members about what goes on in social media and about the many advantages of using them along with the disadvantages and dangers of doing so. The conversation could be steered towards topics that would initiate a discussion about conflicts and the matter of the uploaded photos could be brought up specifically. We at ParaNet believe that only open and respectful dialogue, which enables all household members to freely express themselves about what goes on online, would also allow clear rules and boundaries for online conduct to be maintained. In any case this sounds like a good chance to consult a professional about the household's screen use as a whole. Click here to schedule a consultation meeting with ParaNet.
