Another of God's punishments for not obeying His commandments is forcing people to eat their children:
And ye shall eat the flesh of your sons, and the flesh of your daughters shall ye eat. -- Leviticus 26:29
And thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters. -- Deuteronomy 28:53
I'm not sure where to put it, since no particular commandment is mentioned. It just seems to be "any of the above".
