For dependant pass holder, you'll be paying private rates, even at our govt hospital (Kandang Kerbau Hospital). Which means that the bill won't be very much different if you choose other private hospitals.
There are mummies who have had bad experiences in Kandang Kerbau Hospital and other private hospitals. Ultimately you must decide cos Kandang Kerbau Hospital is SG's 'official' hospital for delivery and they specialise in women and children.
