Advice on 2 month old


My son will be two months old here in a few days and he goes on October 2 to get his two month check up. A friend told me that he will get shots this time, is there any precautions that I should take before I take him? I was told that I should give him a little bit a infant Tylenol before I go into the doctor so after he gets his shots he’ll go to sleep.
