How does the concept of original sin relate to infants?

The doctrine of original sin asserts that all humans inherit a sinful nature from Adam and Eve, as seen in Psalm 51:5. Infants are not exempt from this condition; however, their inability to comprehend sin highlights their need for divine grace. The question of innocence is addressed biblically, asserting that every individual, even at infancy, requires Christ’s atoning work. This adds depth to the understanding of why infants are brought to Jesus, illustrating that they too need salvation through His sovereign grace, thus affirming that all physical death serves to magnify God's merciful nature.
