Ah, the pleasures of being a grandpa. You get to see a child develop, but not have to change its diaper. You get to indulge its passions, but not try to calm it for sleep (either a nap or nighttime). You get to see it crawl, totter, and walk. You get to hear the first communications (which sometimes strain credulity as to the exact word uttered). I, too, have been indulged in this manner. My grandson spoke early and relatively clearly. Some of the words were amazing. His ability to tell a story at the age of one was amazing. But, this is not really about him.
