I may not be entirely sure what I am expecting from this one, mind 
I mean the threads about situations in which the answer depends entirely on your unique circumstances, like 'From what age would you leave your DC alone at home?' - depends on the child/length of time left/access to adult help if needed etc etc.
Or the recurring theme of builders and their toiletting needs (alone at home with young child in scary neighbourhood with unknown tradesman? Or known builder, other adults in the house, easy access to downstairs cloakroom? - totally different)
Or private vs state education - depends on what schools are available where you are, depends on the child, depends on deeply personal preferences.
Or, one of my favourites, 'Am I pregnant?' - 'Love, how on earth would we know. Go POAS, and repeat in a week if no AF forthcoming'.
I accept that MN and other forums would be half empty if there were no threads without clear answers, and I am fully prepared to be told IABU
I suppose I find it baffling that so many people seem to struggle to trust their own judgement: you are worried about leaving your DC unsupervised at home, well, don't. And I think there is a subtle difference between asking 'From what age did you let your DCs alone at home?' and 'From what age do you think my DC can stay alone at home?'
Just musing.
Waddaya think?
Are we less confident in our parenting/other choices than people used to be??
