I haven't done a David update in a while. I think there are lots of things kids try once early on, but I usually count it as a fluke until done regularly. So here are some skills David has actually mastered lately.
Getting good at...
-making arguments. He now connects ideas with "because" and "so." For example, "Don't touch my chair because it's mine." "Turn on the light so I can see." A lot of times he links seemingly unrelated phrases, which sounds funny, but it's impressive to see him trying so hard to explain things logically (or making excuses to get out of doing something).
-cooking. This is actually related to something bigger which is his attention span getting longer. He can stand on a chair while we do a whole baking project together, even if I ask him to wait while I wash a few dishes and clear the counter. He can wait until I give him an assignment. Sure, he might have shown an interest before, but he never had the patience to really participate.
-doing hand motions. (see book cover) Again, maybe he tried to do it before, but I noticed it really clicking for him recently. He probably knows more songs than I'm aware of, but he is seeming more teachable in this regard. I got out a book of kids' chants with motions and have been looking for ones to do with him. It says from 2-5 years but I had tried before with limited success, so 2.5 or 3 years old seems more realistic.
