Infant baptism is the practice of baptizing infants or young children, usually within the context of Christian faith, as a way to initiate them into the church and signify God's grace. This practice is rooted in the belief that baptism is a means of grace and that even infants are in need of salvation, thus connecting them to the community of believers from an early age. Different Christian denominations have varying beliefs about the significance and necessity of infant baptism, reflecting broader theological differences.
