Counting and the ABC's

This morning Tyler and I have been cleaning the house and organizing her toys.  While I was throwing some toys in a bin, I heard Tyler start counting.  She usually gets to 3 and then stops or is distracted.  However, she continued on to 4 and then 5 and so on.  She skipped 8 and then stopped at 10.  It was the first time I have heard her count to 10.  I sat down with her and she did it two more times, still skipping 8 both times.  She can also sing the alphabet song but you can't understand about 1/3 of her letters.  I will try to get it on video and post it later this week.  It's pretty funny!  Time has just gone so quickly; it's hard to believe she is 20 months.
