Did any theologians think that the limbo for children (*limbus puerorum*) is part of purgatory?

Catholics traditionally believe that infants who die before being baptized, go to a place called Limbo. It is not understood whether the belief comes out of a dogmatic teaching of the Church. My question therefore, is: What do the latest teachings of catholic Church say on the existence or otherwise of Limbo?

The Catholic Church professes a belief in the existence of limbo. Although the doctrine on this subject has not yet been defined, does the Catholic Church believe that it is eternal?

Looking at this other question , limbo is an intermediary place for (some) souls to dwell in until they get to heaven. One of the answers to the question mentions two kinds of limbo: - Limbo of hell or of the Patriarchs (limbus inferni seu patrum) - Limbo for children (limbus puerorum) What is (or was) the biblical basis for the existence of these?

This dogmatic statement from the Council of Trent makes it Crystal Clear that we inherit sin from Adam. > If any one asserts, that the prevarication of Adam injured himself alone, and not his posterity; and that he lost for himself alone, and not for us also, the holiness and justice, received of God, which he lost; or that he, defiled by the sin of disobedience, has only transfused death, and pains of the body, into **the whole human race**, but not sin also, which is the death of the soul, let him be anathema; inasmuch as he contradicts the apostle, who says: By one man sin entered into the world, and by sin death, and so death passed upon all men, in whom all have sinned. The Inspired Author shows us that the infant is not an exception. > Therefore behold I was conceived in iniquities; and in sins did my mother conceive me. Psalms 51:5 Is there a **infallible dogmatic statement** from the Catholic Church addressing the eternal destination of the deceased Embryo as a result of his original sin?
