That's not a bad idea, but we're 20 miles away so wouldn't be able to be there for at least half an hour. She's still pretty scared of her mum though, so may feel too pressurised to call us (she has her own phone). What we really want is to stop mum from taking her away from our town, because at least if in our home town then if SD called we're only a minute away, plus she has other 'safe' places to go if need be, on hand in town.
