My 3-week-old cries for hours in the evenings. When does colic typically start and at what age does it go away on its own?

The evening fussiness you're seeing in your 3-week-old is starting around the typical time for infantile colic. Colic usually begins around 2-3 weeks old, peaks around the 6th week, and most babies outgrow it between 3-4 months. So this phase is temporary—your baby's digestive and nervous system will mature and this will ease. As long as these crying episodes are from developmental causes (immature digestion, sensory sensitivity) and not a health issue, there's no need to worry. The AAP uses the 'rule of 3' for colic: at least 3 hours a day, at least 3 days a week, for at least 3 weeks. If your baby has fever, vomiting, diarrhea, or poor weight gain along with crying—talk to your pediatrician.
