Tonight, Davey was being a little fussy before bed.  We both have the stomach virus that just does not want to go away.  So I was holding him and singing to him.  I just make up little silly sings.  Tonight was "Little Boy"  and the lyrics are "little boy" sung over and over.  I can't even remember the tune now, darn it.  Anyway,  I sang for awhile, and he listened, and then I stopped and he clapped his little hands together for me.  Sweetest thing.  He knew it made me smile so I sang some more, and he clapped some more.  :)  And we did that for just a little while.
