Can we please repeat once and for all: SS do not get involved every time a child is lost in a shopping centre/left behind in a restaurant/parents fail to pick up from after school club as a one off. SS are very stretched and struggle to keep up with all the cases of children who are genuinely neglected over a long period.
I consider myself a fairly ordinary parent: not rich, not powerful, no connections. I once lost ds for 10 minutes in Portsmouth. Pushing a wheelchair up the hill on a narrow stretch of pavement and failing to realise he was no longer behind us. We went back and found him, nobody reported us to anyone. SS never got to hear about it- no doubt because I am not the PM. That is the reality of ordinary families and SS.
