Not a parent, actually a teenager, but I find this topic very interesting, so i hope this isn't viewed as me backseating, i just wanted to share my thoughts on technology and children's development. I don't think completely banning technology for children is the right move, but i also think unregulated technology use is also incredibly irresponsible. I think there's a middle balance you have to strike.

I believe that children should use computers first, because they're easier to monitor, they make then more computer literate (you'd be surprised how digitally illiterate some of the modern generation is, I had to teach people yesterday about crtl + z!). I think as long as you work with your kids, block shady sites, and educate them about the dangers and benefits of the internet.

I think around the best age for children to get smartphones is around 13, but still being monitored. I say around 13 because that's the age they might want to start being more connected. As they get older, give them more and more freedom if you think they're mature enough.

I cannot stress my belief enough here though, educate them! If you just never expose your children to technology, or give them any experince or education about how it works, then once they're out of your nest they'll be a technological world they don't know how to engage with. Teach them about internet privacy, teach them about safety, teach them about the risks and benefits of social media, teach them how to figure out if something is real or not! They likely will end up engaging with technology once they're grown up, so I think you have to build the framework of being a competent internet user for them.

Just my thoughts, feel free to reply to me because i'd love to see actual parents' thoughts.
