The lockout period progresses something like 60 seconds, 5 minutes, 30 minutes, 1 hour, 3 hours, 6 hours, 1 day and so on. This should only be possible if the child had sole possession of the phone for days. Not saying it’s impossible, but this appears to be an extreme edge case.

I suspect most of these reports come from either bugs in the software (and some quick Googling suggests this has been the case), or perhaps that even someone (heck, even a savvy child) was trying using some sort of brute force exploit to unlock the phone.

My phone once entered permanent lockout because I left it upside down on a surface that registered a passcode button press every few minutes.
