I Wonder If I'm Growing

I wonder if I'm growing
I wonder if I'm growing
My mom says 'yes, I'm growing'
But it's hard for me to see

My mom says 'eat your sandwich
It will make you grow up tall'
But when I eat my sandwich
I'm hardly bigger at all

I wonder if I'm growing
I wonder if I'm growing
My mom says 'yes, I'm growing'
But it's hard for me to see

My mom says 'Wash your hands now
Then you can go and play'
Hey, I can reach the tap now
For the very first time today

And I think I must be growing
Oh I know I'm really growing
My mom says 'yes, I'm growing'
And now I know it's true
