Salam! I haven't given birth at KPJ Selangor myself, but a few of my mum friends have and they said the staff there quite helpful, best thing is call their maternity ward directly to ask about their procedures and what to bring, sebab each hospital memang ada their own system. For first baby, it's normal to feel nervous about the unknown, but honestly most private hospitals kat Malaysia quite similar, they'll brief you anyway once you're admitted. Boleh jugak ask if they have a tour or info session before your due date so you feel more confident, and don't forget to prep your hospital bag with essentials untuk baby and yourself. Good luck with your pregnancy!
