Before I start giving some context to the post I would like to say I have never been a parent who has tried to control my dcs friends. However, my dd was previously friends with someone who we as a family were very concerned about. The children in the family were all on child protection plans because of physical abuse from parents and they were drug dealers. (Mum now in prison for this) The young person had been picked up by the police a number of times for criminal damage, assault and shoplifting. She was always lying and on occasion stole from our home when she came for tea. They fell out and the young person began a terrible campaign of bullying and also became physical with out dd. It was a very difficult time. Since then our dd has made a new friendship group and things moved on. But I have found out she has struck up a friendship with this girl again and I am very worried. I have noticed a change in her over the last few weeks, she has become very quiet, withdrawn and doesn't share her day with me as she did previously and when she does speak her tone is quite aggressive. I really don't know what to do. I know saying to her not to have anything to do with this girl will not work, in fact it may make it worst. But the friendship is so dangerous. I do not want my dd to become involved in her life again and if they do fall out the consequences from that. Has anyone had a similar situation? How did you get through it? Or am I completely wrong in thinking I can do anything? Should I just let it take its course? But I am worried for her safety and do not want her around people who are a risk to children.
