30 Months: A Growing Vocabulary and Pretend Play

Around 30 months, many toddlers’ vocabularies grow quickly, and pretend play — like feeding a block to a doll as if it were food — becomes more common. Based on CDC developmental milestones, toddlers this age tend to show the following.

Social/Emotional

• Follows simple routines when told, like helping to pick up toys when you say, “It’s clean-up time.”

Language/Communication

• Says about 50 words.
• Says two or more words together, with at least one action word, like “Threw the ball.”

Cognitive (Learning, Thinking, Problem-Solving)

• Uses things to pretend, like feeding a block to a doll as if it were food.
• Shows simple problem-solving skills, like standing on a small stool to reach something.

Movement/Physical Development

• Uses hands to twist things, like turning doorknobs or unscrewing lids.
• Takes some clothes off by themselves, like loose pants or an open jacket.

Caregiving Tip

As pretend play grows, joining in with dolls or play kitchen toys is considered supportive for language and social development. Since wrist-twisting movements increase, it’s also a good time to check that small bottle caps or cosmetic containers are kept out of reach.

When to Consider Talking with a Pediatrician

If a toddler uses very few words, can’t put two words together, or shows no interest in simple pretend play, 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.
