As a pediatric speech-language pathologist, I get questions from parents on a nearly daily basis about speech and language development. They are trying to determine if their child is a “late talker.” While it’s true that all children develop at their own rate, there is a set of developmental milestones that I look for in children.
First and foremost, if you suspect your child is struggling, then trust your gut. Some kids will catch up, and others won’t. How do you know, though, when your child would benefit from seeing a speech-language pathologist? For quick reference, I have developed the 1, 2, 3 Rule. This rule states that at 1 year old, a child will use 1 word or single words; at 2 years old, a child will use 2-word phrases (e.g., “mommy go”; “eat apple”). And at 3 years old, a child will use 3 or more words together to form simple sentences.
The same applies for following directions. At 1 year old, a child will follow a 1-step instruction, such as “go get your ball.” At 2 years old, a child should follow a 2-step direction, like “go get your ball and bring it to daddy.” And at 3 years old, a child should follow more complex, multi-step directions.
More specifically, it is typical for an 18-month-old child to use at least 20 words and have different types of words in their vocabulary. This includes nouns (ball, book), verbs (eat, sit), and social words (hi, bye). At 2 years old, a child should use at least 100 words and combine words into 2-word phrases. The phrases can be combinations the child puts together, like “eat apple.” This does not include common phrases such as “all gone.” A toddler (18–30 months) who has limited vocabulary based on his/her age is often a late talker.
A late talker can have difficulty specifically with spoken or expressive language. It is important to keep in mind that children who are late talkers will have typically developing play skills, motor skills, comprehension (receptive language), social skills, and thinking skills. The idea that “boys talk late” is, in fact, a myth. Development is not gender specific. Boys and girls develop at the same rate despite anecdotal experience saying otherwise.
