The theme of the parent-child relationship in "The Veldt" explores the consequences of technological dependency and emotional detachment. The story illustrates how the Hadley children, Peter and Wendy, develop a closer bond with their automated nursery than with their parents, George and Lydia. This relationship dynamic leads to a breakdown in family communication and ultimately results in tragedy.

In "The Veldt," the Hadleys' reliance on technology to perform parental duties creates a rift between them and their children. The nursery, which can replicate reality, becomes a surrogate parent. As psychologist David McClean observes, "You've let this room and this house replace you and your wife in your children's affections." The children, enamored with the nursery, view it as more real and significant than their parents, leading to emotional distance and resentment.

"Don't let them do it!" wailed Peter at the ceiling, as if he was talking to the house, the nursery. "Don't let Father kill everything."

This quote highlights Peter's attachment to the nursery and his animosity towards his father. The children's emotional investment in the nursery overshadows their relationship with their parents, resulting in a lack of respect and growing hostility. The nursery, representing "everything" to Peter, becomes a source of conflict when George attempts to shut it down, revealing the children's deep-seated anger and entitlement.

The story also suggests that the children's hatred stems from feelings of alienation and unmet emotional needs. The Hadleys' consumer-driven lifestyle and reliance on technology leave the children feeling abandoned and neglected. The children substitute their need for parental love with the whims and desires fulfilled by the nursery. This alienation fosters resentment, ultimately manifesting as rage and hatred towards their parents.

David McClean recommends shutting down the nursery to address the toxic parent-child relationship. He recognizes that the technology has poisoned their familial bonds, turning the children against their parents. Despite the difficulty of this adjustment, McClean believes it is necessary to repair the damage and restore a healthy family dynamic. However, the parents' decision to follow this advice provokes the children's ire, leading to fatal consequences.
