Mathmetician?

Today Caroline was lying in her crib before she fell asleep for her nap. She always talks constantly until she finally falls asleep. She started calling out for me and then saying, "couple of dollars" over and over. We don't know where she picked that up but it's funny. As I kept listening she started counting. Normally she will count 1,2,3 then jump to 8, 9, 10,11. This time she said 3, 4, 9, 10, 11, 12, 14, 15, pond. I'm not sure where pond fits it, but you can't expect perfection at 19 months. She just amazes us more and more with her memory and verbal skills. She can say rhinoceros perfectly and only has a little trouble with hippopotamus. We always wonder what she'll come up with next.
