Mothers possess an innate instinct to respond to their newborn child’s cries. A study published in Psychoneuroendocrinology elaborated on the role of cortisol, a stress hormone, in determining mothers’ behaviour towards their children's cries. It revealed that high levels of cortisol in new mothers caused more intrusive parenting for their infants.
Intrusive parenting here means the mother is quick to step in and becomes overly controlling to reduce the discomfort. With this excessively controlling attitude, the infant’s gestures tend to be misinterpreted. So when a baby cries, the mother might immediately rush to feed them without considering other possible reasons for the crying.
