In general, they will need to sleep two or three times a day, depending on how tired the player lets them get. Toddlers lose energy more quickly than older Sims do, but also replenish it more quickly, especially if they sleep in a crib. Toddlers do not have the comfort or environment motives.

Two toddlers, or a child and a toddler, can use the same toy box or play together at the Will Lloyd Wright Dollhouse or Teeny Tykes Activity Table. Children can play with toddlers who are using skill toys that have the 'Play With' interaction. Toddlers can build relationships with children and/or other toddlers by sharing toys, though this will be slow unless the toddler has learned to talk, and it may not occur with all toys. Apartment Life allowed two toddlers to 'huggle', but before that, toddlers were essentially unable to interact with other toddlers, though two toddlers could autonomously fight over a bottle. Toddlers can cuddle cats and dogs, and may be licked by dogs this will build a relationship between the toddler and the pet. Children can tickle toddlers and give them a family kiss, and the FreeTime expansion pack allows children to teach toddlers a nursery rhyme and sing it with them. Unlike teens, adults or elders, children can't interact with toddlers in many ways. If they have not been potty trained, they also depend on older Sims to either change their diapers or take them to the potty when necessary. They depend on older Sims ( teens, adults, or elders) to feed them, put them into and take them out of their cribs, carry them up and down stairs, and bathe them.

Toddlers require the most attention of any life stage given their lack of independence. Its personality and interests are visible, and it is controllable. When a baby turns into a toddler, most of its genetic traits become visible for the first time. The manual suggests this isn't possible, but it actually is. All toddlers have the Grow Up aspiration and can start earning aspiration points, although they won't be able to redeem them until they are teens, unless the FreeTime expansion pack is installed. It is the youngest life stage that can be created in Create-A-Sim. Toddler is the second life stage in The Sims 2, and it lasts for four days.
