At what age does colic typically begin in infants?

Colic in infants typically begins around 2-3 weeks of age. At this stage, many infants start to exhibit the characteristic symptoms of colic, which include excessive crying that cannot be easily soothed, particularly during the late afternoon or evening. The onset of colic at this age aligns with developmental milestones that may contribute to changes in feeding and digestion, as well as increased sensitivity to stimuli in the infant's environment.

While colic can range in its onset, the peak is generally noted around this timeframe due to the immaturity of the infant's nervous system and gastrointestinal tract. Additionally, infant colic typically resolves by around 3-4 months, making the 2-3 week mark significant in understanding when caregivers might first begin to notice these crying patterns.

Understanding the common onset of colic can help caregivers and health professionals provide appropriate anticipatory guidance and support during this challenging period for new parents.
