The Butler As A Birth Preventative?

One of my sim couples left the baby and toddler with the butler to go out clubbing. When they get to the second club of the night, who sits at the bar, if not the butler who is supposed to be at the house looking after the small ones. As my couple arrives home, the baby and toddler are alone and running to the house and in through the door is the butler.

Same butler passed out alot in the childrens room and refused using the bad assigned to her.

I also once got a butler with the hate children trait....
