Many parents often notice that their children are biting their nails. This is a very common children’s habit. Of course, it does not look very nice. It looks even more repulsive when an adult does this.
Onychophagy is a mental disorder that is expressed as an uncontrollable desire to bite off the nail plate. Studies show that this habit is common among children of primary school age, most often among boys. In adolescence, almost half of all children have this bad habit.
