This morning, Sylvan woke up, then turned, pointed out the window, and made the sign for “tree” (hold your forearm out in front of you, perpendicular to the ground, fingers extended, then rotate your wrist so that you can see the front and back of your hand alternately). There were trees out there.
He then stood up, pointed out the window, and said “truck” (actually, he says something like “tuh”, but it’s different from his other words). He was pointing at a truck.
Amazing.
Did I mention that he turns one next week?
