Is this actually a safeguarding issue ?

[Zaradelorio]

Just wondering about the reasoning behind this. I am a parent to child 1
Child 1 attends a primary and at one point there were issues (unfounded on investigation) that caused a ss referral

Child 2 joins and gets on well with child 1. Play dates etc all going ok.
Then it stops. The school had ‘advised’ the parents of child 2 to try to distance themselves and ‘discourage’ the friendship due to ‘previous safeguarding issues’ no more disclosed but it was justified in the basis of child 2 being adopted classes as ‘looked after’ so the school had a right to pass on this vague info under safeguarding ?

Seeing as the concerns were not found to be anything to actually worry about why should it then affect a child’s friendship ?

Parents might have noticed the absences and gossiped. Other aspects of OPs life might have contributed to the (accurate) rumour of social care being involved. Sometimes it's obvious when someone is struggling a bit and then people embellish. Sometimes they'll be nearly accurate.

Although I do think someone at school might have had a word. People break rules all the time.
