Do babies need to be baptized? No. Mormon doctrine teaches us that babies do not need to be baptized. Some may believe that little children are not saved without being baptized. This can be a heartbreaking perspective for those families who have lost children to premature death through violence, accident, or sickness. It’s hard to believe God would allow an infant’s salvation to depend upon circumstances out of their control, especially the “…many little children [who] have died without baptism!”  Fortunately, The Church of Jesus Christ of Latter-day Saints (commonly called the Mormon Church by the media) teaches a message of hope to families about the plan of salvation, Jesus Christ, children, and baptism.
Mormon Doctrine: The Plan of Salvation
[In the past], many children died very young. The women… had lost children in death, some of them several children. [They were] taught the truth that little children were heirs of the celestial kingdom and that those women might again be with them and with the Savior and our Heavenly Father…” 
The plan of salvation has been taught to people by prophets from the beginning of time. It is still a message of hope, which God reveals to prophets in modern times, since the restoration of the gospel of Jesus Christ. We are children of God, and He loves us, and wants us to return to Him. “The divine plan of happiness enables family relationships to be perpetuated beyond the grave… it [is] possible for individuals to return to the presence of God and for families to be united eternally.”  Relationships are eternal, and parents can be united forever to their children through sacred ordinances performed inside of a Mormon temple (or House of the Lord). “This means that if we are faithful to our covenants [sacred promises with God], our family relationships will continue for eternity.” 
Mormon Doctrine: Children of God
“All human beings—male and female—are created in the image of God. Each is a beloved spirit son or daughter of heavenly parents, and, as such, each has a divine nature and destiny.”  Out of love, Heavenly Father blesses His children with the scriptures, prophets, and the gospel of Jesus Christ. The Savior also exemplified this love, when he invited the little children to come unto Him (Matthew 19:14). When Christ appeared to the families in the ancient Americas (as recorded in the scriptures The Book of Mormon), he “took their little children, one by one, and blessed them, and prayed unto the Father for them.” 
All of God’s children have the opportunity to accept Christ as their Savior, repent, and accept His atoning sacrifice for their sins. However, little children do not need to repent and they are saved through Jesus Christ’s atonement.
And even if it were possible that little children could sin they could not be saved; but I say unto you they are blessed; for behold, as in Adam, or by nature, they fall, even so the blood of Christ atoneth for their sins. 
Mormon Doctrine: Baptism
Little children do not need to repent or be baptized until they are old enough to be accountable for their actions. Before then, they are not fully able to discern right from wrong, and they cannot fully understand the process of repentance. Therefore, until they become fully able to understand, their misbehavior refers to the accountability of their parents. Around A.D. 401, the Ancient prophet Mormon wrote, “I know that it is solemn mockery before God, that ye should baptize little children… repentance and baptism [are necessary for] those who are accountable and capable of committing sin… [Thus,] their little children need no repentance, neither baptism.” 
Babies and children (who died before the age of 8) are automatically saved without baptism. The prophet Joseph Smith (who restored the gospel of Jesus Christ in modern times) taught that “…all children who die before they arrive at the years of accountability are saved in the celestial kingdom (the highest kingdom) of heaven.” 
Baptism is not required of little children under the age of 8. However, when a child turns 8 years old, he or she can choose to follow the Savior’s example. They are old enough to know right from wrong and make their own choice to be baptized or not. “And their children shall be baptized for the remission of their sins when eight years old, and receive the laying on of the hands.”
