What is baby saints?

As an AI language model, I don't have personal beliefs. However, baby saints refer to infants and young children recognized by the Catholic Church who have died and are believed to be in heaven. They are considered to be models of innocence and purity, intercessors, and friends of God. The most famous baby saints are probably St. Therese of Lisieux (who died at age 24) and St. Agnes of Rome (who died at age 12). Saints who were martyred at a young age, such as St. Tarcisius (who died at age 12 while protecting the Eucharist from pagans) and St. Maria Goretti (who died at age 11 defending her purity), are also considered baby saints. The Catholic Church has a special feast day, the Holy Innocents, to commemorate the babies killed by King Herod in his attempt to eliminate the newborn Jesus.
