Babies usually start saying their first words around 9–12 months of age. It’s such an exciting milestone—and once it happens, things really start to take off!
By the time your little one is about 18 months old, you might hear around 50 words in their vocabulary. This is a great sign that they’re getting ready to start putting those words together into short phrases and early sentences.
A simple (and powerful!) strategy we often share in speech therapy is called the “+1 strategy.”
Here’s how it works: when your child says a word, you repeat it back and add just one word.
For example:


By hearing those extra words from you, your child learns how to start combining their own words too. And soon enough, you’ll start hearing short sentences popping up on their own!
Here’s a quick peek at the types of sentences many toddlers and preschoolers begin using as their language grows:
Ages 12–22 months
Declarative (telling): Agent + action, or action + object

Negative: One-word forms like “no” or “all gone”

Questioning: Yes/no questions or asking “what” and “where”

Naming: Saying a few things in a row without “and”

Ages 27–28 months
Declarative: Subject + verb + object

Negative: “No” and “not” used interchangeably

Questioning: Starting to use “that” or “what doing”

Location words: Prepositions like “in” and “on” show up

Conjoining: Using “and”

Ages 28–30 months
Declarative: Using helper verbs like “is”

Questioning: “Where” + noun + “going?”

Negative: “No,” “not,” “don’t,” and “can’t” all get mixed in

Casual speech: Starting to use “gonna,” “wanna,” “gotta”

As your child grows, their sentences will get longer and more complex—and yes, mistakes are totally normal along the way! A helpful trick is to repeat what they say back to them using the correct grammar, without making it a big deal.
For example:


By modeling the correct version in a supportive way, you’re giving your child the tools to grow their language skills naturally.
Most children are speaking in full sentences by around age 5. But every child develops at their own pace, and some grammar rules can take a little longer to master.
