Not sure as a whole but if the parents at my parish wish to do so then the priest with give the child only the Body. I believe Orthodox also commune infants but I may be wrong. Would not be the first time.
I have kept my sons from taking Holy Communion until both understand what they are doing.
Traditionally and historically, the position of Anglicanism was a baptized and confirmed Christian, to receive. That was slightly modified to “confirmed or desirous of being confirmed” for the CoE in North America (the colonial Church and hence forward for the Episcopal Church) originating in the fact that there were no bishops resident in the colonies before the Revolution and for time thereafter. The colonies were under the care of the Bishop of London, who rarely left home. One either went to England to be confirmed, or one waited for the rare episcopal visitation. So, confirmed or desirous of being confirmed became the standard.
Nowadays, don’t ask me, amongst Episcopalians, or other Anglicans, generally. My late rector used to say that the requirements in the 1928 BCP were what he enforced, but it was difficult to conduct an inquisition at the altar rail. If one of the appropriate age, and seeming to know what to do presented himself, he would be communicated.
