DS1(just turned 7) is getting into music - don't want to start getting cd's as we have a family Spotify account - don't really want to get him an ipad or other tablet though as he'll be on youtube before I can stop him
My DS is also 7 and having an ipad for Christmas. He really loves watching random fellas play minecraft and other kids taking tat toys out of boxes.
Hats off to you for fighting it off, but with limitations and safeguards around it (like never on the internet unless in room with adult) I don't think it's the end of the world. DS also has to check every app he downloads with me before he does it.
My son got an ipod touch when he was 7. It was his best present ever! You don't need to have him access YouTube or Safari (internet). My son still has restrictions on these at 10. You can have passwords and hide them, and you can also hide and disable downloading, in-app purchases, deleting apps, anything you want. I have all of it password protected and he has YouTube kids, all his music and quite a few apps he likes. I got a good deal back then for an ipod touch which was usually £180 and got for £120. I believe they will be cheaper now.
