Eh, best you call HKL delivery ward directly lah, sebab SOP berubah-ubah especially post-COVID ni, and tiap hospital ada rules berbeza depending on cases. A few of my mum friends ada yang suami boleh stay, ada yang kena shift basis je, depends on crowd at that time and whether it's normal or complicated delivery. Since your husband dah fully vaccinated, likely okay tapi memang perlu confirm dengan hospital directly so takde surprise on the day, especially if you're planning for epidural or need support person. Manalah tahu they've updated the rules recently!
