When we are talking about developmental conditions, we are typically referring to those that begin in childhood. Stammering is considered to be a developmental condition, which falls under the broader umbrella of speech, language and communication disorders.
It is important to recognise that stammering is not caused by other developmental conditions. However, a stammer can occur at the same time as another condition, which can change how the stammer presents and how it might affect the child.
Some children who stammer may have another (co-occurring) developmental difficulty, for example autism, attention deficit hyperactivity disorder (ADHD) or language disorder. In instances where a child has a stammer and an additional need, they may need more support due to the challenges both conditions pose for them.
A detailed assessment with a Speech and Language Therapist and other healthcare professionals can help you to understand your child's strengths and areas of difficulty, so that they can receive the most effective and tailored support.
