immunization?

Alyssa
So I'm a FTM and I really don't have a clue what I'm doing for shots with my baby! I want him to be happy and healthy but what if I give him something that isn't that a doctor recommends that he doesn't need. My mother and my mother in law also have totally different opioniins about this topic and even though it's me and my husbands baby it has an effect on our thoughts... so id like to hear yours! Are you or are you not immunizing? If so why?
