Dd did a lot if work on the PC and iPads at school from reception onwards. She's y7 now and one if her projects is to code an app, all her homework is to be done and handed in online, I'd imagine there'd be a lot more tech involved in schools by the time your DC reaches it.
Its usual for a toddler to tantrum when something they like is taken away, how did your dh manage his toddlers time with tech? You said you don't want your baby to be a spoilt little shit which makes me wonder if your dh gave his son the tablet or phone or whatever back when he
My own stepson used to be pissed off when his PlayStation had to be turned off, but it wasn't the PlayStation that was the problem, it was the way his time on it was managed, he was given the console as a comfort thing when his parents split, and initially allowed unlimited play time, and then if he created when asked to turn off when guests were there, or for meals, he'd be allowed to just stay on because it was easier than dealing with him crying for hours when guests were there. Dh did similar when he was at hours because he didn't want him to not come So would let him play all day long.
When we had dd I was never going to ban tech, she was using the net from 2 years old, there's a lot of brilliant educational tools online, safety talks also started at two and bits added on over the years. Some children are being their first online device at 11 with a list of safety dos and donts, I keep think if dd was just starting with tech now I dint know where I'd start with the safety stuff and how to expect her to remember it all. There's so much more than not giving personal info to strangers, there's porn, there's IAPs, there's viruses, understanding that what you post is there forever and can be searched by employers etc, what to do if someone sends sexual content, boys asking for nude photos etc etc and it's like other things, they learn it all over time which is why I wanted dd to be taught about it all before she hit secondary school.
People assume when they a child on a tablet they are playing games etc, when they do so much more. Playing a game is the least likely thing my dd will be doing on her tablet, homework or reading a book is what she's usually doing or editing music and photos.
People have been distracting babies in pram so for eons, when I was little I remember my mam moaning about children needing rattles fastened to the pushchairs and how it's sad they looking at plastic rather than the world, her Mum moaned about babies being given food to shut them up when out and about.
I find more adults seem dependant on their phones if anything, we were out for a meal last night and every single table had at least on adult on their phone. I've seen adults tell their kids to out devices away when eating as its rude, and then sit reading Facebook themselves.
Eating lunch at my Mums every other week is similar, all the DC all their stuff away (sometimes tablets but often a book, dolls etc too) and my Mum has to bollock my brother and sister to do the same as they'd spend the whole meal reading Facebook.
