I think this song (like 'Golly Sandra') is about a mother/father/adult talking to a child. They're noticing so many things they love about the child, and how they've become who they are.
"I always screw up,
I wonder how you sing to me."
-I've made a lot of mistakes, but you still love me.
"I've watched you grow up child,
You have made me proud."
-Again - I've watched you progress into a young adult and I've very proud of you.

Just my take on the song.
