Luckily, Shawn came back. A little train time and a few games of Hide from the Witch/Ghost/Animals later, Max was completely won over. He had to sit by him at dinner and then he got Giant Jelly Bean story (pictured above) before bed. Once I got him upstairs I was changing his diaper and he sighed, "I miss Shawn."
One of the little bits of goodness that came along with parenthood that was completely unexpected, is the joy of seeing Max love his extended family. It's crazy how he just seems to know that they are special and loves them with all his little might.
