In our series “The Trouble With 2,” we’ve examined a crucial year for children and the unique challenges it presents. It’s year of rapid development: As Lillian Mongeau explained earlier in the series, “In their 12 months of being 2 years old, most kids graduate from using a few disconnected words to speaking in nearly complete sentences. They also learn to jump, to understand that they may know things others don’t, and to use a toilet.”
What does that change look like? In the video above, we collected a handful of kids to demonstrate this transformation, assigning a range of basic tasks to younger, middle, and older 2-year-olds to show their development. As you’ll see, the differences can be striking.
Correction, Dec. 1, 2017: This video and post originally referred to 2-year-olds as living “their second year.” They’re living their third year.
