Should I be concerned?

Some of Christian's latest drawings. He's only 4 by the way.

This started out as a knife, but then he changed it to a spaceship (by adding more knife-looking things) when he saw the disapproval (horror) in my face.

Do not be fooled by this harmless firefly looking object. It is an axe.

I thought this was a spaceship, wrong again...it's a "weapon".

Based on the previous drawings I was going to guess that this was a bear trap, but this time, my first (oh so innocent) hunch was right. It's a dinosaur.

I'm thinking I should be sleeping with one eye open at night.
