1. The document discusses the importance of skin-to-skin contact between mothers and newborns from a neuroscience perspective. It summarizes evidence that separation from the mother is a form of toxic stress that can disrupt brain development and have lifelong negative impacts on learning, behavior, and health.
2. The author argues that reducing toxic stress for newborns is very easy and involves practices like skin-to-skin contact, attachment, bonding, and breastfeeding that allow the mother's body to regulate the infant's physiology. Public health policies should focus on supporting these early interactions between mothers and babies.
3. Evidence is presented showing that early adversity can get "under the skin" and alter stress response systems

relationships that facilitate adaptive coping.
• Generally occurs within a time-limited period,
which gives the brain an opportunity to recover
