those baptized and confirmed at the Easter vigil are being received into the Church through RCIA, Rites of Christian Initiation of Adults, adults in the case of initiation sacraments being anyone over the age of reason, generally age 7. (This is also the age, incidentally, for confirmation of baptized Catholics. The local bishop or bishops conference can set the date for youth anytime after age 7 in the Latin rite). In fact, the priest who baptizes adults at this time --Easter–must confirm as well. There is a section in the rites adapted for children (the children’s catechumenate–there is no such thing as RCIC) which speaks of baptized children in the same “class” with the unbaptized, who are confirmed at the same time, but there is some disagreement, settled by the local bishop over whether this refers to Catholic children, or only to baptized non-Catholics being brought into full communion. You may take it that your parish is complying both with the RCIA, the national statues, and the particular law of the diocese.
