I'm not saying that a fist grip (or grasp) is Ok, I'm saying that pencil grips may actually make things more difficult if they force a child's hands into mature tripod grasp before they are developmentally ready or they are physically incapable of it (in my case because of double jointed fingers and in DS's case he is low tone and weak). They are worth a try but I wish I hadn't pushed DS so hard to use a grip because it seemed to make things worse. He was able to switch from using a palmar grasp to the grasp he uses now (cross thumb) with reminders. I don't think his original OT tried to make him use a pencil grip. I might try again later if his hands get stronger but right now it doesn't help.
