Difficult decision

[Busy ECE mommy]

I completely agree with Suzie Homemaker!
They would have been gone by now with my rules.
Firstly, an infant needs a nap, whether the parents think so, or not. Put the child and a crib or playpen during regular nap hours.
The aggressive behaviour, whether it be directed at your pet or child, would have had them terminated instantly at the first instance, especially coming from a 5 yr old who knows better.
Move on with new clients, and don't look back.

Thanks for your responses.
I have put him in a playpen at naptime, but he screams the entire time and my two year old can't nap because he's so loud. He woke her up yesterday and today. I started off putting him in a bedroom with the door almost closed, then because of the screaming I put him downstairs in the dining room with the door closed, but he high pitch squeals and yells to the point he starts gagging and he's only left in there for 10 minutes before I check on him, but he just gets himself in such a mess.
I am going to give her notice to terminate the agreement.
I was worried I was being dramatic or unfair giving notice so soon after they started here, but you have assured me.
