Play Developmental Milestones

Play is a child’s main occupation. Babies, toddlers and young children will put effort, energy and attention into play because they find it inherently interesting and fun. Children need to play — it facilitates their sensory, motor, social and emotional skills.

All children develop at their own pace. Below are some general guidelines to consider.

Age Play Developmental Milestones
1-12 months   
  • ​The baby engages in exploratory play — also called sensorimotor play.
  • Play is focused on bonding with caregivers.
  • The baby may explore the parent’s hair, body and face and the parent may encourage the baby’s exploration of objects such as rings, rattles or soft animals.
  • The baby will engage with repetitive movements to experience different sounds, sights, touch and feelings.
  • At this age, play is not just about toys, it’s about back-and-forth interactions — anything from singing a song during a diaper change to cooing and smiling back and forth.
12-18 months
  • ​The young toddler engages in functional play — also called relational play.
  • At this age a young toddler will understand the purpose of a toy and can operate it according to the function.
  • Children learn through play when they can cause things to happen or change. Therefore, cause-effect play is important at this age such as dumping and filling and manipulating toys that twist, turn, crank, make noise or light up.
  • The young toddler also begins to play games such as “peek-a-boo” and “pat-a-cake.”
18-24 months
  • ​The older toddler engages in pretend play — also called symbolic play.
  • The older toddler makes inanimate objects perform actions — such as a doll eating or a car driving through a garage.
  • The older toddler enjoys both solitary play such as building with blocks or completing puzzles and social play such as imitating peers.
  • The joy of movement becomes more self-directed as the older toddler delights in swinging, climbing and sliding; they often enjoy and request extremes of movements.
  • The older toddler can now put together a sequence of several actions such as placing people inside a toy bus and pushing it across the floor.
2-3 years
  • ​The young child will combine actions into entire play scenarios. For example the child will feed the doll, put the doll’s pajamas on and then put the doll to bed.
  • The play experience becomes more social; two or three children will engage with the play theme and take turns or change roles.
  • Pretend play becomes more abstract and an object can be used to represent something else — a block can become a phone, a large box can become a car, a swing can become a space ship.
  • The young child’s motor skills are improving so they can enjoy tricycles and throwing games.
3-4 years
  • ​Play is now highly social and focused on peer relationships.
  • The preschool age child participates in circle time, singing and dancing games, and art time.
  • Group play replaces parallel play and the preschooler shows interest in being a friend.
