Since your baby's colic started at 2 weeks, you're likely approaching or already in the peak phase — which means the hardest weeks may be ahead in the very short term, but there's a clear end in sight.\n\nThe research suggests colic naturally resolves as your baby's gut bacteria balance themselves out. This is a temporary developmental phase, even though it feels relentless when you're in it. Your pediatrician can help if the crying feels severe or if you need support managing it day to day.","sources":"[{\"pmid\":\"35352686\",\"title\":\"The Gastrointestinal Microbiome in Infant Colic: A Scoping Review.\",\"journal\":\"MCN.
