You literally can't set up am Apple watch for kids without a parent-owned iPhone. It's the kind of vendor lock in thst all other companies get immediately chastised for, but Apple always manages to get a pass. I hope they pay their marketing teams adequately for those amazing ways in which they twist public perceptions.
I don’t like that aspect either, to be clear, but the majority of American parents use iPhones and don’t have any plan to leave the platform, and there are other kids smartwatches on the market not made by carriers.
