Milestone Checklist for 2-Year-Old Twins

Twins are just like any other set of siblings, reaching milestones at their own pace.

It’s natural to compare your child’s accomplishments with those of other children, and that also applies when you have twins. If you notice that one twin is ahead of the other in reaching developmental milestones, remember that no two children are the same, even when it comes to twins. If you notice that one of your twins is lagging significantly behind his sibling or other children the same age, you may want to consult your pediatrician.

Motor Skills

Many parents feel like they’re run ragged when their toddler is not only walking but also beginning to run, and parents of twins are doubly busy. According to the American Academy of Pediatrics, by the age of 2, toddlers can pull toys behind them while walking or carry several toys from one location to another. Your twins can stand on tiptoe, kick a ball and climb up and down from furniture without your help. In terms of fine motor skills, 2-year-olds can scribble with a crayon, dump out containers and build towers of four blocks or more. You might notice that your twins have a preference for one hand over the other by this age.


Although it may seem that twins speak a language that no one else understands, they should still reach certain language milestones just as a singleton would by 2 years of age. Your twins should be able to point to an object when you name it and recognize the names of body parts and familiar people. According to the American Academy of Pediatrics, children should be using simple phrases and two- to four-word sentences by the age of 2. Your twins should also be able to follow simple instructions and repeat words they overhear in conversations around them.


The typical 2-year-old brain is working constantly, and you may notice that one or both of your twins are making dramatic leaps in cognitive development. The American Academy of Pediatrics says that your toddlers are beginning to engage in make-believe play and that they can work together or separately to sort objects by shape and color. Children of this age also have a sense of object permanence, which means that they know that they know something still exists even though it’s hidden from view.

Social and Emotional

Twins have a built-in social advantage over singletons in that they’ve always had a playmate, but they still develop social and emotional skills in the same manner as other toddlers. Two-year-olds begin to copy those around them, and often pretend to do the things that they see Mom and Dad do every day, such as cooking or reading a book. By the age of 2, your twins are becoming increasingly aware of themselves as individuals. They realize they are separate from others and begin to appreciate the company of other children. Because of their increasing need for independence, though, you may find your twins also begin to show defiant behavior. This is normal. Two-year-olds defy rules and instructions as a way of trying to exert their increasing independence.
