Ds has a booster jab tomorrow - should I warn him in the morning; when we go to the doctor's or just let the nurse tell him? This is the first one where he has been old enough to understand where that long pointy thing is going to go. I don't know whether to tell him in advance and risk having him get all worked up - or not tell him, lose his trust and have him think that every trip to the doc's might involve a jab.
Then again, I could just tell him and promise that we will go straight to the toyshop once it is done...
Advice please dear ladies.
