DC is in infant school, a child in the class has ADHD. Their parent has been quite vocal on the class WhatsApp about the child's behaviour and diagnosis. From what I've seen and heard the child's behaviour has been disruptive at school but I believe now child is medicated behaviour at school is better.
Speaking to the parent recently, they disclosed that at home things have been bad and that the child threatened the family with a knife, police was called etc. The infant school is small one form entry and I'm concerned if they are this violent at home and threatening to use a knife then whose to say what they would do at school. The child often walks themselves to school so could easily sneak something in.
I feel concerned for my child's safety however no incidents have happened so therefore I suppose there's nothing the school can do and I'm sure for confidentiality purposes they won't talk to me about another child.
Can I/should I do anything about this?
