Is your son's tracking necessary when he is in the care of your W? U, ask yourself....is this just an indirect way of keeping tabs on her?
I could care less about tracking her. I'd prefer we throw the watch in the trash.
What I don't like is the current system where she wants me to make sure he's wearing the watch when he's with me.
My preference is he can wear the watch as he likes. But I do not want to be saying "S, please put the watch on" when he's with me. Kids are smart - I think it sends the wrong message.
