13

Griffin can count to 13, well he doesn't really count actual objects.. but he can say the numbers in order from 1-13.. Here's what he says, "Oneb-two-free-fowar-nine-sick-seben-eight-nine-ten-eleben-twelve-sirteen..."

Also, he thinks that 3 is the new 2.. Anytime Griffin sees or is holding 2 of the same item, he exclaims, "three _____s!"  Three shoes, three balls, three strawberries..  oh dear.  sometimes I think he does it just to mess with me.
