So my 11 year old is starting high school which is around the corner from us and a five minute walk. Her adult siblings have mobiles and she constantly uses mine for Tiktok and WhatsApp. I feel she's too young and impressionable for mobiles but her argument is that her entire class have one. When she's on the laptop doing her homework, she gets distracted and watches YouTube etc and falls behind with her work. I simply find it hard to trust her. On the other hand I want her to stay in touch with her friends over the summer as she won't see them again. I don't want her to feel so left out My other children suggested a cheap basic smartphone which would be strictly monitored by me and password protected. Also it'd be with me at bedtime. But my friends think I'm being unreasonable. Is 11 an OK age?
