Gasp!!

Miles has recently started making this gasping noise.  It's like he inhales air really quickly, making a gasping sound.  At first, I was trying to figure out if something was choking him or something, but then I realized that he has just learned to make a new sound.  When we picked him up from the church nursery this morning, they commented about how he gasps all the time.  He sounds so alarmed!  =)
