What Is Down Syndrome?

Down syndrome is a genetic condition that affects how a child develops, including learning, communication, and physical growth. It occurs when a person has an extra copy of chromosome 21. This changes how the body and brain develop over time.

Children with Down syndrome may learn and develop at a different pace compared to other children. This can affect speech, movement, and everyday skills.

With the right support, many children with Down syndrome build strong relationships, learn new skills, and take part in school and community life.

What Causes Down Syndrome?

Down syndrome is caused by an extra chromosome 21, present from the moment of conception. There are three main types:

It is important to note that the condition is not caused by anything a parent did or did not do during pregnancy. And while the likelihood increases with maternal age, Down syndrome can occur in any pregnancy.

Signs Of Down Syndrome In Children

Some signs of Down sydnrome may be noticeable at birth, while others become clearer as a child grows and develops. Not every child will show all of these signs, and the way they present can vary.

Physical Characteristics

Developmental Signs

Behavioural and Social Traits

Some children with Down syndrome may also have additional medical or developmental conditions. These include congenital heart conditions, hearing or vision difficulties, sensory processing disorder, thyroid conditions, and speech and language delays. Regular health checks and early support can help manage these areas and support overall development.

When To Seek A Professional Evaluation

If something about your child’s development doesn’t feel quite right, or progress seems slower than expected, it can be helpful to speak with a GP or allied health professional. Early guidance can help you understand what your child is finding challenging and what support may help.

Early Signs To Watch For

Some signs that may prompt a closer look include:

These signs can have a range of causes, but they are worth discussing with a professional if you notice them.

The Value Of A Functional Capacity Assessment

A diagnosis can explain why your child is developing differently, but it does not always show how that affects everyday life. Allied health functional capacity assessments focus on how your child is functioning day to day, including how they move, communicate, manage routines, and respond to sensory experiences.

This kind of evaluation helps identify practical ways to support your child’s development.

Allied Health Support For Children With Down Syndrome

Allied health support focuses on helping your child build practical skills for everyday life, communication, and independence. Support is tailored to your child’s needs and often involves a combination of therapies working together. The goal is not to change who your child is, but to support their development in a way that feels meaningful and achievable.

Physical Therapy

Physical therapy supports movement, strength, and coordination.

It can help with:

  • Sitting, crawling, and walking
  • Balance and posture
  • Building strength, especially with low muscle tone

This type of support helps children take part in play and daily activities more confidently.

Speech - Language Pathology

Speech therapy supports how children communicate, both verbally and non-verbally.

It can help with:

  • Understanding and using language
  • Speech clarity
  • Expressing needs, wants, and ideas
  • Social communication skills

Some children may also benefit from alternative communication methods alongside speech.

Occupational Therapy

Paediatric occupational therapy focuses on everyday skills and independence.

It can help with:

  • Feeding, dressing, and self-care
  • Fine motor skills such as grasping or writing
  • Sensory processing and regulation
  • Participating in home and school routines

Support is tailored to what matters most in your child’s daily life.

Next Steps After A Down Syndrome Diagnosis

Getting the right support early can make a meaningful difference in how your child develops skills over time.

An allied health team can help you understand where your child is at and what support may be useful right now. This often includes a combination of speech therapy, occupational therapy, and physical therapy, depending on your child’s needs.

You don’t need to have everything figured out before reaching out. A conversation with an allied health provider can help you make sense of your options and take the next step in a way that feels manageable.
