When a Sim completes a Milestone, it will appear under the appropriate category.

The Simology Panel will show recently completed Milestones for your Sim's current age. Achieving certain Milestones can affect your Sim's behaviour and mood, reward special memorabilia, and unlock new interactions.Īll Sims can achieve Firsts, Life, and Social Milestones, while Toddlers and Infants have additional categories related to learning and development.
