I had one 4 year old who couldn't hold a pencil. He couldn't remember how to pick it up, and didn't have the strength to push it down hard enough on the paper to get any leverage. He couldn't color, had no motor skills whatsoever. He didn't have a dominant hand. His parents liked to leave him at my learning center for an hour, even though he couldn't use the bathroom on his own. He was 4 years old and didn't have the slightest grasp of the alphabet, and couldn't retain anything we taught him. It took a month to get him to count to 10. My theory on all this is, on top of a learning disability/developmental delay his mom was in denial of, he was a natural lefty who was forced to use his right hand but, because of the disability, couldn't, and ended up not developing any motor skills in either hand. Poor kid.
