It is heartbreaking to hold your baby while she screams and feel unable to help. **Crying from colic is not known to shrink a baby’s brain, and her continuing to cry does not mean your comforting has failed.** Colic generally resolves without harming a baby’s health or development. [Mayo Clinic](https://newsnetwork.mayoclinic.org/discussion/mayo-clinic-q-and-a-colic-though-often-stressful-for-new-parents-will-subside/)

Cortisol is a normal stress hormone; a temporary increase is not evidence of brain damage. The research behind frightening claims about stress and brain development concerns prolonged adversity, such as abuse or neglect, without adequate supportive caregiving. Your holding, rocking, and responding are meaningful support—even when they cannot stop the crying. [Harvard Center on the Developing Child](https://developingchild.harvard.edu/key-concept/toxic-stress/)

**You do not need to meet a 10-second deadline.** Responding promptly to a newborn is recommended, but that is not a stopwatch rule. You cannot spoil her by comforting her, and no parent can soothe every cry. Briefly watching ordinary squirming is reasonable; newborns still need substantial help settling. [American Academy of Pediatrics](https://www.healthychildren.org/English/ages-stages/baby/crying-colic/Pages/Responding-to-Your-Babys-Cries.aspx)

Evening crying, difficulty settling, and a red face can all occur with colic, which usually improves by about 3–4 months. However, **six hours of inconsolable crying each day deserves another conversation with her paediatrician**, especially if they did not know the full duration. They can reassess her feeding, growth, and possible other causes. If she is currently crying continuously for hours and cannot be consoled, seek prompt medical advice rather than assuming every episode is colic.

Seek urgent medical care for a temperature of **38°C/100.4°F or higher in a baby under 3 months**, poor feeding, markedly fewer wet nappies, or green vomit. Call emergency services for trouble breathing, blue/grey colour, or unusual floppiness or difficulty waking. [AAP](https://www.healthychildren.org/English/ages-stages/baby/crying-colic/Pages/Responding-to-Your-Babys-Cries.aspx), [Seattle Children’s](https://www.seattlechildrens.org/conditions/a-z/emergency-symptoms-not-to-miss/), [NHS](https://www.nhs.uk/baby/caring-for-a-newborn/soothing-a-crying-baby/)

Keep using gentle comfort and take turns with another caregiver if possible. If you become overwhelmed, put her on her back in an empty, safe cot and take a few minutes to regroup; never shake her. Taking a short break is recommended, responsible care. **Your job is to offer care and safety—you do not have to make every cry stop.** [AAP](https://www.healthychildren.org/English/ages-stages/baby/crying-colic/Pages/Responding-to-Your-Babys-Cries.aspx)
