Language Development & Disorders
Children's communication skills are developing from the moment they are born. During a child's early years there is rapid growth in their expressive, receptive, and social language skills. Although most children will experience typical language acquisition and development, there are some who may require support.
When a child's expressive language skills (vocabulary and word combinations) do not begin to emerge when we would expect, they may be demonstrating late language emergence (commonly termed a 'late talker'). If a child's expressive and/or receptive language skills do not continue to develop as we would expect, they may have what is termed expressive and/or receptive language difficulties (also known as expressive and/or receptive language delay). By age 5 (sometimes earlier), if a child is demonstrating persistent difficulties with language development, they may later be identified as having developmental language disorder (DLD).
When parents express concerns about their young child's language development with others, they sometimes hear, "s/he'll grow out of it," or, "don't worry until s/he's three." Unfortunately, these common misconceptions delay parents from acting on their concerns and seeking a speech-language pathologist's advice.

The best thing you can do as a child's guardian is to have your child assessed by a speech-language pathologist (SLP) so you can make informed decisions. You’ll find out how your child’s development compares to what is expected for children their age based on standardized, norm-referenced test results, language sample analysis, and other clinical evaluation procedures.
Assessment usually requires one hour, but the sessions can be shorter based on the needs of the child. The SLP will speak with your child to get a detailed case history which includes your observations of your child's language skills in daily life. You may be asked to complete questionnaires. The SLP will observe your child carefully as they interact with you and her and engage in play. The may engage them in activities to set them up with opportunities to demonstrate what they can do. For example, if the SLP has a bottle of bubbles that the child wants, will they say "bubbles"?
For older preschool children, the SLP may be able to use formal tests to evaluate their language skills. This may include asking the child to label pictures in a book or point to pictures that they describe. While doing this kind of testing, children take turns in a fun game or activity and take breaks as needed.
There are various approaches to providing support depending on the needs of the child and their guardian(s). For some young children who appear to have late language emergence, the SLP may introduce the child's guardian(s) to 'language facilitation strategies' to apply in daily life. These are specific strategies known to help support these children. Follow-up visits consist of checking progress, layering in strategies, advancing the child's goals, monitoring response to intervention, and assessing their progress and development. Some children will benefit from additional direct therapy with the SLP if they require support with more specific language targets (e.g., sentence structure, verb tense, pronoun use, categorization).
