Baby Not Nice

You have a little infant doll that goes with your Loving Family dollhouse that you have designated "Baby Not Nice." While all the other dolls are contentedly eating around the dinner table or preparing for a camping trip with a herd of My Little Ponies, Baby Not Nice jumps on top of their heads, kicks food off their plates, and pushes them out of the camper. I'll ask, "Sophie, what are you doing?" and you explain, "Baby not nice!" I think the baby is your id.
