Don't be angry.
As I know, if you wanna at "瑪麗"生, must register at X育醫院, and all the monthly check up will also be at X育醫院.
I do the same proceduce 4 years ago as give birth for my son.
The staffs in X育醫院 were very nice to me also with "瑪麗"'s doctor+ nurses.
X育醫院's staff told me cos there are not so many HK Mami so they were treasure us very much....
