That would be the norm in many eastern Catholic churches but not in the Latin Church (unless there is the danger of death). See the canon law of the Latin Church:
ResponsibiltyCan. 99 Whoever habitually lacks the use of reason is considered as incapable of personal responsibility and is regarded as an infant.
ConfirmationCan. 891 The sacrament of confirmation is to be conferred on the faithful at about the age of discretion, unless the Episcopal Conference has decided on a different age, or there is a danger of death or, in the judgement of the minister, a grave reason suggests otherwise.
Can. 883 The following have, by law, the faculty to administer confirmation:
1° within the confines of their jurisdiction, those who in law are equivalent to a diocesan Bishop;
2° in respect of the person to be confirmed, the priest who by virtue of his office or by mandate of the diocesan Bishop baptises an adult or admits a baptised adult into full communion with the catholic Church;
3° in respect of those in danger of death, the parish priest or indeed any priest.
EucharistCan. 913
§1 For holy communion to be administered to children, it is required that they have sufficient knowledge and be accurately prepared, so that according to their capacity they understand what the mystery of Christ means, and are able to receive the Body of the Lord with faith and devotion.
§2 The blessed Eucharist may, however, be administered to children in danger of death if they can distinguish the Body of Christ from ordinary food and receive communion with reverence.
Promotion and RestrictionCan. 914 It is primarily the duty of parents and of those who take their place, as it is the duty of the parish priest, to ensure that children who have reached the use of reason are properly prepared and, having made their sacramental confession, are nourished by this divine food as soon as possible. It is also the duty of the parish priest to see that children who have not reached the use of reason, or whom he has judged to be insufficiently disposed, do not come to holy communion.
