Is baby dedication biblical? What is child / baby dedication?

from the old testament

• The Old Testament includes no record of formal baby dedications, yet it provides the foundations for what such a practice represents. From the earliest times, God claimed children as His own and called families to acknowledge His authority over them. Under the Mosaic law, the firstborn were consecrated to the Lord and redeemed by sacrifice, reminding Israel that every child ultimately belonged to God (Exodus 13:2; Numbers 18:15–16). These acts expressed gratitude for life and dependence on God’s sustaining care.
• Hannah’s story provides one such example of this devotion. In her longing for a child, she vowed that if the Lord granted her a son, she would dedicate him to His service. When Samuel was born, Hannah fulfilled her vow, bringing him to the tabernacle at Shiloh and presenting him to the Lord (1 Samuel 1:11, 27–28). Her act of worship showed a parent’s humble recognition that children are a sacred trust from God.
• God also instructed His people to teach their children His truth. Parents were to speak of His commands at home, on the road, and throughout daily life (Deuteronomy 6:4–7). Proverbs reinforced this calling by urging parents to train their children in wisdom and righteousness (Proverbs 22:6). In these commands, God made clear that the family is the first place of spiritual instruction.

from the new testament

• Mary and Joseph demonstrated this kind of devotion when they brought the infant Jesus to the temple, presenting Him to the Lord in keeping with the law of Moses (Luke 2:22–24). Their act echoed Hannah’s earlier faithfulness, showing gratitude for God’s gift and a willingness to raise their child according to His purpose. Though this moment fulfilled a legal requirement, it also reflected the heart of dedication—a joyful acknowledgment that children belong to God.
• The apostles also reiterated the Old Testament emphasis on godly training within the home. Paul urged parents to bring up their children “in the discipline and instruction of the Lord” (Ephesians 6:4) and reminded believers that every generation must be grounded in the knowledge of Christ’s love (Ephesians 3:17–19).

implications for today

Parenting is one of the greatest joys and responsibilities God can give. The Bible’s focus is on parents' daily call to love, teach, and model faith for their child. That is, God entrusts parents with the sacred task of organizing their home and life around scriptural truth so that they will come to know Him. As a parent, your goal is to help your child come to know Jesus, to see in you a living example of grace, prayer, patience, and trust in God.

A baby dedication is not required, but many parents choose it as a way to publicly thank God for their child and to promise before Him and their church family to raise that child according to His Word. If you decide to participate in a dedication, treat it as more than a joyful occasion—it is a sincere commitment. You are declaring that, with God’s help, you will honor Him in your parenting, teaching your child to love and follow the Lord.

Whether or not you publicly dedicate your child, remember that God does not expect perfection; He calls for faithfulness. As you lean on Him, He will equip you to provide a loving, biblically grounded environment where your child can grow to know and trust in Christ.
