Ian doesn't ever get to hear the music during the service since he is in the nursery. The dedication was at the beginning of the service, so he got to hear the first few songs. Ian is a very observant little boy and likes to take everything in before he makes up his mind as to whether or not something is okay in his book. In this first picture he is taking it all in.
Truly enjoying the music and clapping along. He liked it so much that, after the dedication, he didn't want to go to the nursery. I might have a hard time convincing him that the nursery is more fun than the adult service from here on out!
