Amazing Vocabulary!!!!!!!

Okay, so I am going to brag... But, it is a mother's right. Carter has always had an impressive vocabulary. Well when I picked him up from school he said to me,
"Mommy, guess what happened at school today?"
"What?"
"The chrysalis turned into a butterfly! It was so Coooo!!!" (cool)
I was amazed. He continues to tell everyone about the stages of a butterfly! He is fascinated with it!!
