My daughter has had access to a tablet since she was 12 months old. She's 5 currently, but she's not a tablet zombie as I so commonly see reported of toddlers with free access to phones. Just yesterday, my daughter freely, without my intervention, put away her tablet to play with a child who happened into the room we were in. She never touched it again until we were bad into the car and begged me to leave and play with her new friend outside instead of ask for another set of headphones for the friend.
This is the result of my international teaching of my daughter about how we interact with devices. As someone who grew up with the internet in elementary school, I feel extremely confident, I can keep this up even as my preschooler turns into a kid into a teen.
I just think it's a shame that I'm surrounded by parents with intention of teaching her kids about how to responsibly use their devices or they want to deny their kid access at all like somehow their child will magically manifest all the skills they need to deal with infinite stroll once they turn 18.
