It's so heartache to hear of such news, and that PD also too much, guess he must be thinking he's the only PD in PR area, so got attitude, but his clinic also not very crowded type, dun know why he behave like that.
As for jabs, thought it'll be easier to give while the child is younger as once they are older and understand what's injection, it'll be an uphill task to convince them to go. My gal did not take the jab but my nephew 2 years younger than her took it sometime back. At that time, it was already very difficult to bring her to the doctor, and once we took her for the flu vaccination which all of us went coz going for holiday, she was screaming like anything in the clinic, so embarrassing.
