Life skills were introduced in The Sims 2: FreeTime. They are skills that a Sim can learn to unlock special interactions or abilities. Unlike other skills, they are not learned incrementally. A Sim will not have a life skill until he or she has learned it completely.
This skill can be learned by reading a book from any bookcase. Once learned, it allows a Sim to "check" on babies. A thought bubble will appear indicating any motives needing attention. The symbols for hunger, bladder, and so forth are the same as they are when older Sims need something and began waving at the player.
Allows a new interaction: "Repair relationship with...". When this interaction is used, the Sim using it will start trying to fix the relationship between the two Sims who have a romantic relationship problem. If a couple is divorced, their relationship cannot be repaired.
