Rob knows who Alex is?

Technically, knowing the names of the numbers and the order they come in is just part of counting. You also need to know:

1. that when you're counting objects, the highest number you get to = the total number there are.

2. that each object in an array is only counted once.

3. that wherever you start counting, you reach the same total.

4. that no matter what you're counting, counting itself happens in the same way.

Alex repeated the trick for Michael this evening, with peas. I started counting them and she added "five, six." But she couldn't answer the question "how many peas are there?", and so she isn't really counting.
