Sayang, I haven't personally given birth at Hospital Kajang, tapi a few of my mum friends there mentioned the process pretty straightforward, you'll need your antenatal card, IC, and insurance details (or payment arrangement kalau private). Best thing is call their Labour Ward directly to ask about their specific procedures and what to pack in your hospital bag, sebab setiap hospital ada sedikit berbeza, and they can tell you exactly what they provide versus what you need to bring yourself. Congrats on the pregnancy!
