I have an 11 year old son, 5 year old daughter and baby # 3 on the way. We were recently talking about planning the new baby’s baptism and my son asked me, “Why are we punished for Adam & Eve’s sin?” I told him that we are all sinners and that every time we sin, we make a choice just like Adam and Eve did. He then asked why babies have to be baptized to get rid of original sin if they have never sinned before. My answer was because Jesus said so.
However, I know you CAF members have a much better answer that will make more sense to an inquiring 11 year old and his mom.
