Oh MK, even in this early phase of DS' development, I can sympathize! It can be a real parental rollercoaster, can't it? He first spoke extremely early and in sentences for a week, then went silent for a few months, by which point I had deluded myself into thinking it was a fluke. As you know from my recent posts, it wasn't. He's also recently started skipping "4" when he counts, I think just to irk his father. He went through similar phases of fake knowledge suppression whenever he's gotten bored with the material, and is still on a kick of defining everything by what it isn't (e.g. blue is "not-red-not-green-not-yellow..." You get the idea...)
Hang in there. Trust your instincts.
