A popup will inform you of the scenario requirements and outcomes. To start the scenario, click the New Scenario tab in the main menu and select the Too Many Toddlers scenario. It will be available for two weeks until November 17th, 2021 so if you want to play the scenario, you will have to start it before then. The Too Many Toddlers scenario will only run for a limited time. Today, a new scenario has been added to the game. Yesterday, The Sims 4 added a new feature called Scenarios to the game challenge-style goals for players to work towards.
