Aihhh I feel your pain lah! Memang sekarang KK sangat crowded, a few of my mum friends also kena postponed appointment. Boleh try KK Jalan Ipoh atau KK Setapak, depa usually less crowded than Damansara area ones, tapi memang kena call dulu to confirm ada slot available ke tak sebab online booking selalunya outdated jugak. Kalau still fully booked, dapat juga tunggu ada cancellation, or cuba ask the clinic counter directly if ada walk-in slots on certain days, some KKs do prioritize walk-ins for newborn registration!
