Mother's who especially love newborns fall into two scenarios, one is where family members unite to help care for the child, sharing the mother's exhaustion and allowing her to more quickly enjoy the joys of child-rearing. The other is the subconscious, outward display of feigning for others to see, and for oneself as well - though, this act isn't necessarily bad for the mother herself.
Many women use the act of feigning love to hypnotize themselves. When everyone around believes a mother's love for her child is instinctive and obligatory, they too use this method to hypnotize themselves, gradually accepting their maternal identity and quickly growing to love their baby.
Some, like Jade's wife, find life too difficult and exhausting that even such self-hypnosis is ineffective.
Who would instantly like a child, given the grueling, tormenting task of caring for an infant, if it weren't for a touch of masochism?
