What Am I?

I'm a child

Short but mighty

Pulling my mother out of bed

I'm a child 

Smart and witty

Cooking for my children who are my siblings

I'm a child 

Sneaky yet aware

Pouring the vodka from my father's glass

I'm a child 

Small but grown

I have a brain most don't

I'm a child

Sixteen now

Living on my own

I'm a child

Looking back

While my questions reign

When was I ever a child?
