An 18-month-old typically has a vocabulary of 15-20 words or more.
At this age, toddlers are starting to understand more than they can say. They may be able to follow simple instructions, like "Come here" or "Give me the ball." They are also beginning to use single words to communicate their needs and wants.
Some common words that an 18-month-old might say include:
* **Mama**
* **Dada**
* **Ball**
* **Dog**
* **Cat**
* **No**
* **Up**
* **Down**
* **More**
* **Gone**
It's important to remember that every child develops at their own pace. Some children may have a larger vocabulary than others, and that's perfectly normal. If you are concerned about your child's language development, talk to your pediatrician.
Here are some things you can do to encourage your child's language development:
* **Talk to your child frequently.** Use simple words and phrases.
* **Read to your child every day.** Point out pictures and name objects.
* **Sing songs and play rhyming games.**
* **Encourage your child to imitate sounds.**
* **Be patient and supportive.**
As your child grows older, their vocabulary will continue to expand. By the time they are two years old, they may have a vocabulary of 50 words or more.
