Isaac learned all of his toddler skills with time to spare. His favorite toy was the peg box and played with it constantly. His favorite baby-sitter was Bella. Bella opened his mind to new possibilities and outcomes even as a toddler.
As a young child Isaac watched other kids play soccer/football with their father's. His dad only played chess so Isaac soon learned how to as well. He actually beat his dad a couple of times and soon got very good.
