Child labor

Kostadis was away for several days, and I needed manly help in the yard, so Nick had to buck up and work.

Mom said we are going to play "turn over the plant beds" game. She said
it was going to be super fun, but I am not sure. It's kind of hot out here.

She gave me my sandbox shovel and said "dig". So I dig. 

Then she made me spread mulch.

And push heavy things around.

And she didn't even give me any water to drink, so
I had to find my own.

So what are the child labor laws in California?
