We're Growing is a song sung in The Big Dog Problem about how Peg and Cat are growing and have grown. The word "growing" is used both figuratively (as in maturing) and literally (as in getting bigger).
Peg's mother: It seems like only yesterday, you used to creep and crawl.
You couldn't walk, you couldn't talk, you couldn't do much at all.
Then you grew a little bigger and turned into a tot.
You made a sound and soon, I found you liked to talk a lot.
You were growing, growing, bigger than before.
Every day you grew some more, you were growing.
Cat: When I was just a kitten, I was tall as a cup of tea.
But with some time, I hit my prime. Now I'm tall as three.
Peg: We're bigger than we've ever been and we know how to count.
We learnt to share and compare to get the same amount.
Peg and Cat: We're growing, growing, bigger than before.
Every day we grow some more, we're growing.
Peg's mother: And now you're getting older and I'm giving you new chores.
Peg: But we were scared.
Cat: Not prepared--
Peg: ---to see you on all fours.
Peg: We couldn't go behind the dog. He saw through our disguise.
Cat: He made us grow, 'cause now we know---
Cat and Peg: ---we can't judge based on size.
We're growing, growing, bigger than before.
Every day we grow some more.
(Big Dog barks to the tune of the chorus)
