How can I make vaccine shots easier on my baby?

It differs according to each babies since babies have their own personality. For my daughter, it was to distract her with anything. It could be a nursery song, or a stranger (nurse) making silly faces at her or even videos of herself on my phone. Crying babies also distracts her and she forgets about the jab. For my son, nothing can ever distract him so it's hold him tight, quickly administer it and then carry and cuddle him while he wails lol. I find this way he subsides crying pretty quickly as compared to doing it the way I used to with my daughter.
