There's a type of parents who worry too much about what bad may happen to their children. Thinking that they are preventing some possible evil, they may be constantly spying on their children, or secretly searching their things and interfering in their lives without the kids' knowing it. As for their other adult worries in comparison with ordinary people, they can't be called worrywarts.
So I'm in search for a single word—in case there is one in English— to describe those parents, both regarding their gender and disregarding it. In my native language, there are not the one-word equivalents I can think of to use a dictionary.
Maybe there is also a saying or a slang expression for such parents and for what they are doing to "guard" their children in that way?
