Some of my favorite Stephen phrases...
*morning day
*Sorry, Charlie - he picked this up from his parents.
*this morrow? - When I tell him something is tomorrow, he'll say "this morrow?"
*Do you unnerstand? - usually said to Paul, another phrase he heard his parents use
*How many times do I have to tell you? - He said this to me once, another mommy phrase.
*What did you say to Paul? - Being a typical oldest child, Stephen must know everything I say to anybody else.
*I love you, Mommy! - This is definitely my favorite!
