Kids are considerably different from each other on the level of hand dexterity, coordination and liveliness. For some kids it is from nature to have more difficulty to do some kind of dainty work requiring exact coordination of eyes and hand movement, for example to lace, and they are, looks like, are not in power to control themselves from crushing things around. Such awkwardness almost always is seen from the birth and hardly can serve as reason of some kind of disorder. But it is very rare when child who had good coordination before suddenly turns to have severe awkwardness, that can be consequence of neural or muscular system disorders.
