IPS matrix screens were kinda ok even in 2007, when I was selling them, but they had a super shitty reaction time, so everything had quite visible trails. That was the time when a good CRT was still a professional choice. But now, and for the last 10 years or so, IPS became much better, and kept their great color palette, so there are zero reasons to look elsewhere, a standard midrange monitor does the job. And if you want even less trouble, just buy a designer a used imac - that’s an almost complete workplace, and apples retina screens are also IPS. This is what several development (mobile, web) companies I worked in did.
Well, you can go fancy and buy new ones, but the used ones are in abundance - rich mac fanboys switch to every new model that comes out
My position is that if at the end of a day your kid still has the same amount of limbs and eyes, it’s fine. My kids are 8 and 10 now, they’re active, and they more or less know what’s dangerous and what’s not, because they fell of things face-first a couple of times.
Overprotecting can also be dangerous just for development. When my daughter was like 5, she had a friend af the same age, a girl who DIDN’T LEARN HOW TO RUN, because her mom was scared for her. I’m happy we didn’t go crazy about safety. Your kid wants to jump off a cupboard? You can just comment that it could be painful, and maybe show a picture of a fractured ankle x-ray.
