It is troubling just how many intelligent, educated parents I see are perfectly happy to give children and babies a tablet or phone to placate them.
On the other hand, have you thought about the difficulties of handling this as a principled parent?
You can either turn your child into a social pariah during key developmental years, or spend hours of your and their lives trying to regulate a device that is designed to capture and waste your attention (something I personally rejected as an equal waste of my time and effort, when I took my journey to no smartphone), or do what almost every other parent does, and just give your kids a smartphone.
