Dd is 12.5 and has an itouch and a phone (not smartphone). She's reasonably sensible regarding their use as far as I can see. Up to now she hasn't been 'into' her gadgets as much as some teens but I think that's changing.
She's not interested in Facebook but she's on Instagram like her friends and also texts a fair bit. In term time I try and encourage phones and gadgets off by 8.30ish but it's not completely set in stone and there's a bit of leeway. However I've realised that her phone and iPod are still by her bedside. She told me tonight (quite late) that a girl she knew was on Instagram as she saw her iPod flash so she had a look.
Would it be unreasonable to insist that phones and gadgets are left downstairs overnight for the sake of good sleeping habits?
What are your rules and do they differ in term and holiday time?
