I'm not a baby anymore!

My poor Sam, he's been dealing with pink eye and hasn't had a single nap this week. I was fixing lunch and he was looking at his high chair (which is now Rainey's, like so many of his things) and fingering one of the straps the boy starts BAWLING. I went over and he just clung to me crying and when he could finally speak I asked him what was wrong and he said, " I'm not a baby anymore!" :(
Sweet boy (who crashed about an hour ago and is snoring contentedly).
