24 Months: Two-Word Phrases and More Active Movement

Around 2 years old, many toddlers start putting two words together and become more physically active, like kicking a ball. Based on CDC developmental milestones, toddlers this age tend to show the following.

Social/Emotional

• Notices when others are hurt or upset, like pausing or looking sad when someone is crying.
• Looks at your face to see how to react in a new situation.

Language/Communication

• Points to things in a book when you ask, like “Where is the bear?”
• Says at least two words together, like “More milk.”

Cognitive (Learning, Thinking, Problem-Solving)

• Holds something in one hand while using the other hand, like holding a container and taking the lid off.
• Follows two-step instructions, like “Put the shoes in the closet.”

Movement/Physical Development

• Kicks a ball.
• Runs.
• Walks up a few stairs with or without help.

Caregiving Tip

As toddlers become more physically active and range farther, it’s considered helpful to double-check safety around stairs and thresholds. Once two-word phrases begin, expanding what a toddler says into a slightly longer sentence when you respond is considered supportive for language development.

When to Consider Talking with a Pediatrician

If a toddler isn’t putting two words together at all, can’t follow simple instructions, or doesn’t attempt to run or climb stairs, checking in with a pediatric provider may be helpful. This information isn’t a diagnostic tool and doesn’t replace advice from a medical professional.
