A Speech & Language Development Guide

How Children Should Engage with Others

Typically respond to voice and sound, establish eye-contact, and use a social smile (smiles when spoken to, or when others smile at him/her).

By 8-9 months:

Children should respond to their name and easily shift attention from objects to people (joint attention).

By 1 year:

Children are expected to copy simple actions of other, e.g., clapping;  use a variety of gestures, e.g., give items, show items, point, shake head “no,” reach for objects/to be picked up; and follow pointing.

1-2-year-old children:

Typically pair pointing with vocalizations, engage in verbal turn-taking present, respond to speech with eye-contact, and wave “bye-bye.”  They typically play next to other children; use social words such as, “Hi,” “bye,” “thank you,” and “please;” and protest by vocalizing, “no.”

2-3-year-old children:

Should use words to get attention, begin to adapt speech to the listener and engage in short conversations.   They typically communicate a variety of functions including comments, asking for help, and social greetings.  Children this age are expected to watch other children, briefly join in their play, and participate in simple group activities.

3-4-year-old children:

Typically engage in longer conversations (at least 3-4 turns), use words to request permission, make conversational repairs, and start telling stories and jokes.

4-5-year-old children:

Should effectively communicate their feelings.  They typically take turns in play, separate from primary caregiver easily, and begin dramatic play (acting out whole scenes). Children this age are expected to use words to invite others to play and resolve disputes with peers.

By 18 months:

Toddlers should use close to 20 words.

By 2 year:

Toddlers should use at least 50 words, put together two-word phrases, and ask who, what, and where questions.

By 30 month:

By 3 years:

Children should consistently use at least 3-word phrases and mark grammatical elements like mommy’s, walking and toys.  They typically use words to describe locations in, on, and under.

From 3-4 years:

Children should use pronouns like I, you, me, we, and they.  They typically ask when and how questions. They should put at least 4 words together in a sentence.  They may still make grammatical mistakes, like “I goed to school.”

By 4, they talk about what happened during the day and use about 4 sentences at a time.

From 4-5 years:

Children should use sentences that have more than one verb, but they may still have some grammatical error. They tell short stories and keeps conversations going. They also typically name some letters and numbers.

Most children follow a similar path of language development, however, there are always individual differences.

At some ages, there is a wide range of what is considered “typical,” but there are markers specialists look for along the way that indicates when children may need intervention.

When a child is missing skills in their communication development, it can result in breakdowns and frustration at home and be detrimental to their learning and ability to make friends in school.  

At Kid Matters, we use gold-standard evaluation measures, and treatment rooted in research to provide the tools children need to strengthen their communication skills.  

Early identification of communication deficits results in faster progress and better outcomes.  If your child seems off track with any of the skills listed above, do not hesitate to call for a free consultation. Or visit our speech-language pathologist.
