Is my 13-month-old son required to attend Sunday Mass?

Full Question

Sometimes my wife and I drop our 13-month-old son off at my mom's house while we go to Mass. It just occurred to me that since my son is baptized, he has an obligation to attend Sunday Mass. What is my obligation to see that he attends Mass?


Children under the age of reason are not obliged to attend Sunday Mass. However, they should be familiar with attending Mass by the time they are seven years of age (the accepted age of reason). They ought to be attending Sunday Mass regularly by the time they start school.
