My DD1 who is a total drama queen and can not handle any pain (e.g. yesterday she cried when she had pins and needles LOL) did not even flinch. No crying, nothing, lol. I prepared her and talked about it for a week in advance. She was worried at first and then came around to the idea and we got her a treat for after.

You're also not supposed to give panadol anymore. Makes the vaccine not work as well.
