DS8 hated all that too. He never liked crayons or coloring. He did like the water painting books. When he was 2 he "finger painted" with q-tips, didn't like playdough and didn't like dirty hands. I didn't think of OT because we were busy with speech therapy. He went to K with basically no writing skills but it came pretty quickly when he had to write in class every day. He still doesn't like it though. He prefers to use the laptop and he even has Dragon Speak Naturally to dictate to.
