I vividly remember the first "joke" I shared with my infant son when he was about 1-1.5: He was pointing to colours and my job was to say it out loud. At one point, I deliberately called black as "green" and he instinctively skipped to the next color but quickly did a double take and jumped back to the previous one, thinking he misheard it. I repeated "green" and he looked at me and started laughing (I was expressionless). Mind, this was the first time I had done something like this in any context. And he got it! It was a joke. Now, at about 5, he gets puns and sarcasm is hit'n'miss. As a side-note, the whole thing as to how his appreciation for jokes is evolving is interesting. But the most important thing for me as a parent is enjoying these moments of laughter.
