I received First Holy Communion in the first grade, at age seven. It was a solemn occasion that I remember well; boys wore suits & girls wore white communion dresses. As children we understood that we were receiving the Body and Blood of our Lord, for we had been so instructed for months before the holy event. Age seven is the age of reason IIRC.
THAT’s why Communion should not be given to two year olds.
My youngest daughter will receive her First Holy Communion on Mother’s Day. After reading this article, I asked her if she thought a two year old should receive it as well. Her response is simple.. “no way, a two year old can’t even poop in the toilet by themselves. They shouldn’t get the Body and Blood of Jesus YET!” I am still laughing! Even at her young age, she knows that this Sacrament is blessed and special—reserved for the more mature.
Plus also not just be intructed months ahead of time, but also make first confession as well. The years just prior would be the preperation for the kid.
