It is our genetic nature as a species to believe as young children that our parents and elders are right. We watch them to see what's what. Later on we can judge for ourselves and rebel if need be, but when we're just months old, or a year or two, and a parent looks at us with impatience, or disgust, or disdain, or just leaves us there to cry and doesn't answer us even though we're longing to be embraced and nurtured, we assume that something must be wrong with us. Unfortunately, at that age it's impossible to think there might be something wrong with them.
