My Little Sister

I have a little sister,
They call her sweetie pie.
She sits in the corner and pretends to cry.
At night she takes up all the bed,
In fact last night she slept on my head!

I have a little sister,
She still wears a nappy,
She plays all day to keep herself happy.
She's clever, intelligent and really smart,
But absolutely messy when it comes to art.

I have a little sister, She loves to eat,
In the middle of the night I can smell her feet.
She acts like an adult and calls my brother Mister,
I just can't believe that she's my sister.
