Sonia M. Mcalister is a Paediatrician based in Perth, WA, Australia. She looks after babies, kids and young people, with a steady, practical approach when things feel a bit scary or uncertain for families.
In her day-to-day work, Sonia helps with infections and other illnesses that can affect children’s health in different ways. This includes whooping cough (pertussis), tetanus and diphtheria. These are serious conditions, so getting the right care early can make a big difference.
She also treats issues like strep throat. In many cases, this is something families notice as a sore throat that won’t settle, along with fever and kids feeling quite unwell. Sonia focuses on checking what’s going on, making sure the right tests are done when needed, and guiding families through treatment and follow-up.
Rheumatic fever is another concern she manages. It can be linked to certain throat infections, and it needs clear monitoring over time. Sonia helps parents understand what to watch for, and why ongoing care matters even after a child starts to feel better.
At times, children can also be dealing with tick paralysis, especially in areas where ticks are common. Sonia guides families through how symptoms are checked, what signs mean it’s time to come in urgently, and how treatment is handled to help a child stay safe.
Her clinical work comes from experience caring for children with these kinds of conditions. She pays attention to how each child is coping, not just the illness on paper. That means listening to what parents are seeing at home, and working out a plan that fits around school, sleep and everyday life.
Her education and training supports her role as a paediatrician, with the knowledge needed to assess children, recognise warning signs and coordinate care. She aims to keep conversations plain and calm, so families can make decisions without feeling rushed.
For families in Perth and the wider WA area, Sonia’s role is about clear steps and steady support. When a child is unwell, it helps to have someone who can explain what’s happening, what comes next, and when to seek help again.
