I may not talk, but I count like a genius

Alex again is excelling with his memory and understanding of numbers. He started counting to 100 in multiples of 10 awhile ago. Just the other day, he counted to 100, then counted backwards, in multiples of 10! He was also attempting to count all numbers on the way to 100!! He's understanding the concept and blowing us away. We still can't get him to tell us how his day was but I may not need a calculator in the future!!!
