The baby therapist Thomas Harms explains clearly and thoroughly why babies cry and how parents can safely and successfully regulate their babies' emotions. While it was once believed that prolonged crying strengthened the lungs and had health benefits, therapists today understand that babies only feel secure when their emotions are mirrored and acknowledged. Baby crying carries a message to the environment that needs to be deciphered. However, crying presents parents with significant emotional challenges and can lead to stress and uncertainty in daily life. Current research shows that parents can better understand and support their infants when they remain connected to their own feelings and bodily sensations. Harms describes in simple terms how parents can engage in mindful self-observation.
