because all her friends have one 
its her birthday in 2 weeks. DH is saying lets just get her one. DM says the same (although I don't think DM fully understands!)
So DD now thinks she's getting an iphone.
I am adamant she's not getting one. 12 yo maybe, definitely not 7.
I'm suggesting instead a phone for her room, allowing us a bit of control over who she phones and who she answers the phone to.
AIBU? Any other 7 year olds out there with mobiles??
