Logan's favorite things are his blanket (a.k.a "B"),  Mo-Mo dvd (a.k.a various series of Elmo dvd's) and anything Thomas the Train.  He also loves to put on sunglasses.  The pair he is wearing in the photo below he received at a school birthday party from his friend, Blaze.  However, the flowers on the glasses makes me think they were meant for a girl.
