- Children with Down syndrome have lots of potentials, they are strong visual learners and have great social skills and like to have fun like all kids

- Low muscle tone can also affect everyday skills such as feeding and dressing independently

- Many children with Down syndrome also experience hearing difficulties which can affect communication, expressive language and speech clarity

- Down syndrome affects a child’s learning ability and can make it harder for them to concentrate

Important things to know

The most important thing to note is that Down syndrome is just a part of someone. It does not define them. People with Down syndrome are people first and foremost and deserve the same respect and treatment that you would give any other person.

The preferred language to use when referring to someone with Down syndrome is “a person with Down syndrome” rather than “a Down syndrome person”.

Down syndrome is not a sickness or a disease, it is a genetic disorder or chromosomal anomaly that occurs at the time of conception.

Every person with Down syndrome is unique with their own talents, abilities, thoughts and interests and like everybody else they have their own strengths and weaknesses.

Children with Down syndrome can contribute greatly to their families and wider communities provided they are given the right supports, services and opportunities to enable them to reach their full potential.
