The Catholic Church believes that life starts at conception and that every person's life is sacred.

  “Your faith spoke for this child. Baptism for this child was only delayed by time. Your faith suffices. The waters of your womb — were they not the waters of life for this child? Look at your tears. Are they not like the waters of baptism? Do not fear this. God’s ability to love is greater than our fears. Surrender everything to God.”

  Before I formed you in the womb I knew you, and before you were born I consecrated you.

  As regards to children who have died without Baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them. Indeed, the great mercy of God who desires that all men should be saved, and Jesus’ tenderness toward children which caused him to say: ‘Let the children come to me, do not hinder them,’ allow us to hope that there is a way of salvation for children who have died without Baptism. 

 There is also an understanding of “baptism by desire”  in which it is taught that people who die while unbaptized are supposed to have been baptized by their “explicit desire” to receive this sacrament. This may also apply to children whose parents intended to baptize their child after birth.
