"Infants do not take communion..."
Canon 710 - With respect to the participation of infants in the Divine Eucharist after baptism and chrismation with holy myron, the prescriptions of the liturgical books of each Church sui iuris are to be observed with suitable due precautions.
From the Code of Canons of the Eastern Churches, promulgated by the authority of Pope John Paul II, 1990.
Since 1910 it has been the practice of the Latin Church to give Communion to children from the age of seven (see decree Quam singulari, Aug 8, 1910). The ancient custom of giving Communion to infants had largely ceased in the West by the 12th century, but it is still maintained in Eastern Churches. The Council of Trent decreed that it is not necessary to give the Eucharist to children before they have reached the age of discretion, but it did not condemn the practice (see Session XXI, Decr de comm., canon 4).
From The Code of Canon Law: A text and commentary, Canon Law Society of America, 1985.
No charge for the clue.
If you think this was a kindly way to educate someone (who is not yet Catholic) about the Catholic faith, then I too, have a clue for you....
As I said, the practices of my future parish as they have been given to me say that children must be baptized and should be educated in the sacraments and aware of the meaning before they participate.
But thank you for being so kind and helpful.
