But a 6y doesn't need a computer. Just like they don't need toys, books, a trampoline, etc. But soemtimes they moght like one and use them sensibly and responsibly, and technology doesn't mean they stop doing other stuff.
I find the whole attitude on MN sometimes very bizarre over this, as if one thing means the exclusion of others.
As I said, my DD does have a laptop of her own and she has internet access too, and I don't always hover over her when she is online either. I am teaching her sensible use of computers and the internet, and teach her about keep safe online. 6 and 7 is not too young to learn this and hopefully she will grow up with this ingrained into her. I also have security settings and can monitor her computer and internet use remotely anyway.
What does she use it for?
Education City, Mathletics, typing up stories on word, making slideshows of photos, Club Penguin, she uses google images to import pictures into word or powerpoint, etc.
We have never had to restrict use. She does 15 minutes of mathletics a day, and then maybe half an hour more of something. Sometimes a but more, and then will go days doing nothing. If she is told she can't go on it, she doesn't, no issue. If she is told to turn it off she does, again with no fuss.
Yes she could use my laptop. But I would rather she didn't for various reasons.
It doesn't have any negative effect on her development or behaviour either.
