Honestly I'm not sure about the exact walk-in process kat Hospital Putrajaya sebab I delivered both mine kat private hospital, tapi from what a few of my mum friends mention, you should probably call ahead la even untuk government hospitals, at least to confirm they boleh accept you dan ada bed available, especially kalau first pregnancy you want everything settled kan. Bayaran-wise, government hospitals memang jauh lebih affordable compared to private, but I'd suggest you ring the labour ward directly to ask about the deposit, procedures, and whether you need to register awal-awal or boleh betul-betul walk in, mums I know siapa deliver kat government hospitals always recommend calling first to be safe.
