If? As far as I am aware almost every nation unequivocally allows parents to track their children, largely because the parents are responsible for the actions of their children even while unsupervised. Most phones already support that from the get-go, things like location sharing for family is a feature that both Apple and Android have supported for ages, and I believe it's a parental control thing that can be enabled easily.
Though personally I only believe that is okay to do without consent from the kid up to about 12 years old. After that teaching your kid how to make an emergency call or alert that shares their location live to a person they trust (usually parents) would be more prudent and teaches the kid both responsibility while giving them the tools to stay safe. And 16 or above it's absolutely no longer okay to track a kid unless there are real problems that would require it, like an already existing criminal record or health issues that may require access without the teen being able to initiate the thing.
What I absolutely never support are apps like life360 (or however that crap is called) that monitors and logs the entirety of everything that happens on the kid's phone. That's as much of a privacy invasion as installing a camera in your child's bedroom and bathroom / shower. It's okay for infants to ensure they don't suffocate themselves in the crib, but once they gain basic autonomy and are no longer in danger from dying by vibing that's simply no longer appropriate.
