Unless it would be to confer a drop of the Precious Blood upon the tongue of the infant at the time of their baptism
At the EC parishes that I’ve recently attended (Melkite, Ruthenian), it is a drop of the Precious Blood for infants/toddlers, but they commune every Sunday, not only at their baptism.
The thinking behind communion for infants is that seeing that it is a mystery to us as adults, infants and small children only have a little less understanding of what it is that they are receiving (on an intellectual level) than we as adults have.
Also it is believed that all who are baptized into the Church understand on a spiritual level what, or rather
who it is that they are receiving whether they are infants or adults.
I’ve been thinking about this a lot recently seeing that my eldest daughter is at the age where normally she would be preparing for her first communion, but she is autistic and preparing her for her first communion at this stage of her life is problematic, and looking at the Eastern tradition of infant communion seems to solve the problem, before it’s a problem.
Never mind her level of comprehension, a great worry of mine is weather she would even receive if presented with the Holy Eucharist, or the possibility of, God forbid, her spitting it out.
It can sometimes be hard to get her to eat things that she likes on a regular basis, let alone something she’s never had. Had she been receiving communion since infancy, it would be completely normal to her and wouldn’t really present this dilemma.
BTW how beautiful is this clip!
