Sims can age up using a birthday cake, which can be purchased in buy mode, purchased from a supermarket, baked at home, or purchased in a restaurant. Twenty-four hours after that warning, the player will get another alert stating that the Sim can age. Whenever a Sim is two days away from the next age transition, a warning will pop up in the top right corner alerting the player that there are only two days to either get the Sim's aspiration score up (if the Sim is in the negative), or that there is nothing to worry about since the Sim's aspiration is already high.
