Place a ice cube for few seconds on that area

Completing the full course of vaccination is very important .

Vaccinations safeguard your child from deadly diseases. They are given to boost your child's immunity so that his body can fight infections.

Don't skip any vaccinations thinking that they aren't important or because some one else did the same. Vaccinations are done for a reason.
Kindly don't skip any

I would also recommend you to meet a Pediatrician and talk about the same.
Discuss about your baby's vaccination schedule with your Pediatrician.
