This need not worry you. They are all right as long as they know how to form a proper grip. When they need it, they can use it. Keep handy a few triangular vinyl pen grips that slide onto pen barrels. They are remarkably useful for teaching a good grip.
Triangular pencils have their advantages, too.
Children don't need these things all the time. In each class, there are usually a few who do, and they won't all need them on the same day. It is not suited to the demanding control of pen movements. Copyright 1999 Gunnlaugur SE Briem . All rights reserved.
