You can't touch players defined as essential, and you can't even damage children. Other than that, go wild.
These will be the ones to endure a fate worse than death...Something so sinister only the most darkest souls could unleash...Bury them alive with baskets. I have, what I like to call soul trapped 1 child in a undisclosed location. During my travel I acquire more baskets and place them on top of her when I return. I am pretty sure she has not eaten in about 13 days or so.
