Cedar, who most of you know has ASD, will be four this month, and still doesn't really talk. He counts, and based on his play with number cut-outs he can order number symbols. The other day he read the time off a digital clock, though with 3, 6 not 36. And the other day he repeated "[Cedar], get down" when we told him to get off a coffee table.
He names colors too. It's funny because there's a little girl who is a year ahead of him at church, who was a prodigious talker in nursery, but her mom posted on facebook that she doesn't know her colors. So you just never know with kids.
Something I ran across the other day was that Hekka had a 4 word rotating vocab at this age. Cedars is more like 2 words, but I'd forgotten Hekka doing anything like that.
