children have very thin skin and are prone to scarring and infection if the burn is not properly assessed and treated. it would be best (since i have no ability to examine your son and determine the extent and seriousness of the burn blindly over the internet) to see a medical provider -- either an urgent care facility or er.
my 2yr old son burned his leg with hotwater it started to blister can i treat this at home or i take him to the er?
