Baby - Special Delivery?

It seems when I told Joseph that Simon would be coming soon, he thought VERY soon. The other morning the doorbell rang when a service man was arriving at our house to check the heater. As soon as Joseph heard the bell, he exclaimed "Baby! Naimah!" ("naimah" is how he says "Simon") and then went down the stairs as fast as his little legs could carry him. I guess he thought Simon would be coming right to the door!
