UM have a very good child Paediatrics, Professor Dr Subhashini Jayanath. Among the best in Malaysia
but they will do a lot test - hearing, speech, eye test before you landed an appointment with her.
My journey for my daughter took me almost 2 years until i landed appointment with her for an 1 hour session.

The journey to identifying a developmental disorder involves multiple tests and continuous consultations with general pediatricians.
Speaking of UM and based on my experience, first you will undergoing multiple tests and ongoing consultations with general pediatricians. they will guide you to perform more observation over time.
Well, it’s important that we allow sufficient time and provide the necessary support to ensure a proper diagnosis, rather than rushing to conclusions after only a few months of interaction.

Check this link , i been to Prince court and got charged Rm680/session and UM charge me Rm15 for each session.

for me, Dr Ranjini S Sivanesom is consider the best in the Malaysia. but waiting time is just too long to get an appointment for her at KL GH -Kuala Lumpur Women and Children Hospital unless you sees her at Prince court each time.
