The Second Child

Am I, the second child,
An item prised above the other?
Why does the second
Get treated different to the brother?

Am I, the second child,
A second attempt at the son?
Practice makes perfect
So try for a better one?

Am I, the second child,
Treated as a tiny infant bird,
May I scream and squawk
Yet never be heard?

Am I, the second child,
Your last? Your babe?
Look at me now, your second child
Has grown into something wild.
