There’s a wide range of speech development in children that is considered typical, but there are also milestones a child should hit.
When my older son was 18 months old, I realized he didn’t babble. He made sounds, but his language development wasn’t organized. Turns out, this was an early sign of my son’s autism. But not all language delays are the sign of something serious. If your child isn’t hitting his milestones, just ask your pediatrician – he should be able to steer you in the right direction.
12 to 15 Months
Your toddler should have a wide range of speech sounds in their babbling (like p, b, m, d or n). They begin to imitate and approximate sounds and words modeled by family members, and typically say one or more words (not including “mama” and “dada”) spontaneously. Your toddler also should be able to understand and follow simple one-step directions.
18 to 24 Months
The average toddler vocabulary is about 20 words by 18 months and 50 words at 24 months. By age 2, they should start combining words into two-word simple sentences. They should also be able to identify common objects, common pictured objects and body parts.
2 to 3 Years
Your toddler’s speech should explode during this year. Their vocabulary will increase exponentially and their sentences should be multi-worded and show the beginnings of complexity. They should also understand more; for example, commands with multiple steps like, “Please put the book on the table and come here.” They should begin to identify colors and comprehend descriptive concepts (big versus little, for example).
