To leave dd(5) at home with dd(12) for 10 minutes

Just that really. 12yo wants to look after her sister while I pop to the shop...

I wouldn't do it, not until younger one is older, more like 7.

I would

If 12 year old is sensible then I would.

Of course it's fine.

Yup. Decent 12 year old is the key. And keep it short.

How well behaved is the youngest?

My 4.5 year old batters the living crap out of her older sisters if they don’t give her her own way. Not a chance they’d be able to cope with her in an emergency.

Yes of course. It's only ten minutes
