A Speech & Language Development Guide
How Children Should Engage with Others
Infants 0-6 months old:
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.
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.”
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.
Typically engage in longer conversations (at least 3-4 turns), use words to request permission, make conversational repairs, and start telling stories and jokes.
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.

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.
Speech-Language PathologistI equip children with the tools needed to increase their speech and language skills so they can reach their full potential socially and academically.
