When your older brother was very young, he loved the series, Blues Clues.  Here is what the TV show was about:

A human host welcomes his preschool audience to the “Blue’s Clues” house, where his animated puppy, Blue, helps find three clues to something they are trying to figure out. Viewers are invited to participate, with Blue and her friends stopping to listen to what the audience has to say. – Google

He was obsessed with this show.  I have a picture of him at his third birthday with a Blues Clues cake.  I think your Grandmother Dot made it for him as she used to do so often.  I hear you gals don’t see her too much.  I hope you get to see your brother and wish him a Happy Birthday.  Give your niece a big kiss for me too!  🙂
