Perhaps the level of love and care for a baby/child are positively correlated to the severity of challenges parents face during pregnancy and eventual pain a mother endures in the natural childbirth. Hazing rituals exist for a reason. Will the nature of parental bonds change when Amazon delivers your baby via an electric stork/drone ? Will abuse and neglect increase the way it does with step-children, for example. It's admittedly a dark thought but worth contemplating since that technology seems inevitable and is already possible through surrogates as noted by another comment.
Edit: ADHD, dark though disclaimer.
