What happens when you leave a baby crying?

When a baby is left to cry, it can lead to stress and anxiety for the infant, as they may feel abandoned or unsafe. Prolonged crying can increase cortisol levels, which may negatively affect their emotional and physiological development. However, some parents choose to allow their baby to cry for short periods to encourage self-soothing, but it's essential to respond to a baby's needs, especially in the early months. Consistent responsiveness fosters a secure attachment and emotional well-being.
