We were putting his toy eggs away in their box. We counted one, two, three, which I know he can do (although I'm not sure he knows what it means), then I stopped counting and he kept going!
I tried it a second time but he was into something else by then, so it wasn't as clear, but he definitely sounded like he was saying four, five, six in the right order.
Is this even possible? Does anyone know when children develop an understanding of numbers? I would say his verbal ability is generally good, but not out of the ordinary for his age.
Sorry if this sounds like a boast - that's not my intention. I'm just surprised and hoping someone can enlighten me!
