We have a giggler! This morning, Jack spit up a little bit. As I was changing his lovely poopy diaper and Jason was wiping down his face with a warm washcloth, he giggled! I know it was a giggle because we both heard it and he did it several times.
It must have been the washcloth on his chin that tickled him.
I imagine I will be trying to recreate this scenario several times a day. I want to hear him giggle again! It was so darn cute.
