How Many Words Should My Child Be Saying? A Quick Guide To Vocabulary Development
<span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif;"> Parents often wonder how many words their children should have at different ages. This seems like a simple question, but there's not always a simple answer**. Vocabulary development** can be relatively variable among children of the same ages. However, there are some general guidelines: <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif;"> It's important to note that when talking about vocabulary, we have to be careful to state what type of vocabulary we are looking at: **expressive vocabulary** (the number of words children //use// when they talk) or **receptive vocabulary** (which is the number of words children //understand,// and is almost always significantly higher than expressive vocabulary). The above numbers represent //expressive vocabulary,// or the number of words children typically use at these ages.
 * Children typically speak their **first word** somewhere around **12 months**. Some children, however, take up to 16 months to utter that long-awaited **first word** and this is still considered to be within the range of typical.
 * At **18 months,** children typically use between **50 and 100 words** (but we don't worry too much unless they have fewer than 20)**.**
 * At **24 months,** children usually have an expressive vocabulary of **200-300 words** (but we don't worry too much unless they have fewer than 50).
 * At **3 years,** children can have anywhere from **500-1,100 words** in their vocabulary.
 * By **5-7 years,** children have an expressive vocabulary of **3000-5000 words**.

And it's even more important to note that at least one study (Hart and Risley, 2006) found that the significant variability in children's vocabulary at the age of three was strongly related to the amount of talking parents did with their children. Specifically, they found that parents who used 'conversational' speech with their children (talking about what they did, what they saw and what they thought about what they did and what they saw-- basically just making //conversation// with their children on a regular and on-going basis) had children with significantly higher vocabularies and IQs at age three than children whose parents used mainly directive speech (get this, do that, come over here). The differences in language and IQ remained at age nine as well. <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif;"> <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif;"> <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif;"> <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif; text-align: left;"> Mean length of utterance (number of words in a sentence) about equal to age ( this is only accurate up to age 5) <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif; text-align: left;">  <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif; text-align: left;"> Number of steps in a command a child is able to follow increases with age <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif; text-align: left;">  <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Arial,Tahoma,Helvetica,FreeSans,sans-serif; text-align: left;"> Correct use of all parts of speech by age 6 years     Pragmatics  Explaining information to a listener   What does listener know and not know?  Initiate and maintain a conversation  Grasping main idea without getting lost in details  Make inferences <span style="background-color: #d6d0e5; color: #444444; display: block; font-family: Constantia; font-size: 150%; text-align: left;">[|Normal development chart] [|Developmental chart] This is a good chart that puts everything together.
