I don't know - see #445.
The question is, do we admit someone to Communion for the sake of a ceremony and a photo op, thereby imposing on that child a sure future of spiritual starvation?
Good question. I don't know what the best answer is. I think about it every year while discussing with my second graders their future reception of the Sacrament of Confession and their upcoming Holy Communion. Too many of the parents think that their childs second confession can be 14 mos after the first when the kids make their First Holy Communion. (The Religious Ed program provides opportunity for the sacrament 2 or 3 times during our school year.) And that same laxness is evident with Holy Communion, too.
One old enough to be admitted to Communion should be old enough to be "responsible" for trying to go to Mass. For most young ones this would mean asking the parents or another trusted adult to take them.
This is different from being "culpable" in the event that their requests are rebuffed. Certainly, at some point in the child's further development they become masters at getting driven to school dances and football games and the mall to be with friends. When the child is at that point, he certainly has the means to arrange transportation to Church, should he desire it.
