Sean Hisses at Dr.'s Office

We have this book that was given to Sean when he was an infant from Grandma Linda called Squeak Squeak. It's Sean's favorite. On the first page it reads "Squeak! Purple puppy looked around. Where did that squeak come from? Did you squeak he asked Snake? Not I said snake, I only hissss." Sean is learning to mimic that sound. It's so cute. During one of my prenatal appointments we recited that book for Sean and he started "hissing."
