I am pretty sure the whole TV/screen time thing stemmed from childhood obesity. Not because using technology is a bad thing.
My 3.5 year old (summer baby, starts school in September) has his own iPad, leap pad and uses our laptops. Along side lots of physical activities, his enormous collection of books. He is massively technically savvy.
Technology is everywhere, from the machines that made your car and sofa so affordable, to the fact that technology is ingrained in the curriculum. My preschool has kindles, that the children can use for reading, maths and just fun! Most schools near us have coding club starting from 7 too.
It would be an incredible disadvantage for you child to not use technology. Alongside a childhood brimming with lots of different experiences.
I was a bit funny about my DS using iPads and things at the start, but he has learnt so much from using educational apps and even watching you tube videos. It has really helped with his numeracy and language skills.
He has a French app (they do French in preschool) and can fluently count to twenty in both French and English. I can't get passed 10... he knows the first few letters of his favourite videos and types these into the search bar etc.
It's so different from when we was young, I learnt to touch type in my early twenties, my sister who is 10 years younger than me, learnt to touch type at 13, because using a keyboard was just a normal thing!
Reconsider the tech rule, oh and stop being so judgey.
