About Paediatrics
Paediatrics is the medical care of babies, children and adolescents. Paediatricians look after childhood illnesses and infections, growth and development, feeding and nutrition, asthma and allergies, and the management of longer-term conditions. Care spans routine check-ups, immunisations and developmental assessments through to the diagnosis and treatment of acute and chronic problems, with referral to paediatric sub-specialists (such as paediatric cardiology, respiratory, gastroenterology or endocrinology) when needed. Because children are not simply small adults, doses, milestones and conditions differ from adult medicine, and care involves the whole family.
Conditions and treatments commonly covered
Areas commonly seen in paediatrics include:
- Childhood infections and fever
- Asthma and allergies
- Growth and nutrition concerns
- Developmental and behavioural issues
- Vaccinations and health screening
- Common newborn and infant problems
What to expect at a consultation
An initial consultation usually involves a discussion of your symptoms and medical history, a focused examination, and any tests needed to reach a diagnosis. The specialist will explain the findings, walk you through your options — including non-surgical approaches where relevant — and set out the likely costs and next steps before anything proceeds. If a procedure is recommended, it is reasonable to ask what it involves, the expected recovery time, the risks and the alternatives, so you can make an informed decision at your own pace. It helps to keep asking questions until you fully understand the plan.
Preparing for your appointment
- Bring referral letters, past reports, scan images and a list of your current medications.
- Note your main symptoms, when they started and what makes them better or worse.
- Write down the questions that matter most to you, and bring a family member if it helps.
After your consultation and follow-up
Depending on the diagnosis, you may be given medication, referred for further tests or imaging, scheduled for a procedure, or asked to return for review. Ask what warning signs should prompt earlier contact, how to get your results, and who to reach if you have questions between visits. Keeping your own copy of reports makes future care and any second opinion easier.
Costs, subsidies and financing in Singapore
For subsidised care at a public (restructured) hospital, a referral from a GP or polyclinic is generally needed; private specialists can usually be booked directly at full fees. Ask upfront for an estimate covering the consultation, tests and any procedure. Depending on the treatment, you may be able to use MediSave for approved day-surgery and procedures (within set limits), with MediShield Life or an Integrated Shield Plan helping for larger inpatient bills. Purely cosmetic procedures are not claimable. If cost is a concern, it is worth asking whether a subsidised referral is possible, and comparing written estimates between providers before you commit.
How to choose the right paediatrician in Singapore
Beyond credentials, it helps to match the specialist to your specific problem. Consider whether their sub-specialty fits your condition, how often they manage or operate on cases like yours, which hospital they admit to (and whether it suits your budget and insurance), and how clearly they explain your options and costs. Accreditation can be confirmed on the Register of Specialists and registration on the Singapore Medical Council register. Independent reviews are a useful signal for communication and experience, but weigh them alongside credentials rather than on their own.
Questions worth asking at your first consultation
- Are you an accredited specialist in the area my condition falls under?
- What are my options, including non-surgical or watch-and-wait approaches?
- How often do you treat or perform this, and what are the typical outcomes and risks?
- What is the full estimated cost, and what can I claim through MediSave or insurance?
- Are you comfortable with me seeking a second opinion?
Verifying credentials
In Singapore every practising doctor must be registered with the Singapore Medical Council, and specialists are additionally listed on the Register of Specialists maintained by the Specialist Accreditation Board — you can search both to confirm a doctor’s registration and field. The letters after a name (such as MRCP, FRCS or FAMS) reflect postgraduate training and fellowships, but the key question is simply whether the doctor is an accredited specialist in the area relevant to your care.
When to consider a second opinion
A second opinion is reasonable before major surgery, for a serious or unclear diagnosis, or when a recommended treatment feels aggressive or uncertain. Good specialists welcome it. Bring your reports and scans so the second doctor can assess the same information. You are entitled to a copy of your medical records to take along, and seeking another view will not offend a good specialist.
Common questions
When should my child see a paediatrician?
For ongoing or worrying symptoms, feeding or growth concerns, developmental questions, chronic conditions, or when a GP recommends specialist review.
Are childhood vaccinations necessary?
Yes — Singapore’s National Childhood Immunisation Schedule protects children against serious infections; a paediatrician can advise on timing and any catch-up.
What’s the difference between a GP and a paediatrician?
A paediatrician is a specialist in children’s health, which helps for complex, chronic or developmental concerns; GPs handle much everyday childhood illness.
Do I need a referral to see this specialist?
For subsidised care at a public hospital you generally need a GP or polyclinic referral; private specialists can usually be seen directly.
How can I verify a doctor’s credentials?
Check the Singapore Medical Council’s Register of Medical Practitioners, and the Register of Specialists for accredited specialists.
