When Seth saw Bryan put on his PJ's he was THRILLED to realize that he had similar PJ's in his own drawer. He ran to his room and came back yelling, "We are matching!!!" And boy are they ever!
Seth is the spittin' image of his dad at age 4 (almost 5). They are even both number 4 in the family line-up (even the exact same boy/girl order!) They have the same temperament and quirks. And they are both super easy to fall in love with!!!
