Theoretically, I'm in favor of Holy Communion for infants and those who have not reached the age of reason. They can receive an increase in sanctifying grace ex opere operato if they are in a state of grace, and the presumption is that they are until they have reached the age of reason. I've just seen a fair bit of the abuse, as I described earlier, that's extremely disedifying and disrespectful to the Blessed Sacrament in the practical order. Perhaps additional regulations need to be in place to govern the practice. I've also seen a good amount of mis-handling of the Communion cloth that's used in lieu of a metal paten, so much so that one Byzantine priest I knew abandoned the cloth and used a paten. This cloth is supposed to catch fragments of the Blessed Sacrament, but then it's handled roughly and badly as soon as Communion ends so that most of the particles so caught would be scattered everywhere.
