What Is Cortisol (And Why Isn’t It the Enemy for Infant Sleep)? [create a daily schedule](/sleep-schedule) [printable sleep guides](/free-printables) [sleep quiz](/quiz) Cortisol often gets a bad rap, painted as the villain of stress.

This fear often stems from a misunderstanding of stress itself, failing to differentiate between tolerable stress and toxic stress. Tolerable stress is brief, infrequent, and occurs within the context of supportive relationships that help the child adapt. Learning a new skill, like falling asleep independently, might involve some temporary fussing or crying. When a parent is present, attuned, and responsive, this brief stress can actually be a growth opportunity, helping the baby develop self-regulation skills. The parent\'s presence acts as a buffer, co-regulating the baby\'s nervous system. Toxic stress , on the other hand, results from strong, frequent, or prolonged adversity without adequate adult support. This is the ki
