If you're breastfeeding, dairy you consume can pass into your breast milk—so when you eat or drink milk products, your baby is receiving those milk proteins too. If your baby has a milk sensitivity, even small amounts in your milk can trigger or worsen colic-type crying.\n\nThe research suggests trying an elimination diet: cut out all dairy for about 2-4 weeks and track whether your baby's fussiness improves. If symptoms calm down noticeably, it's a sign your baby may be sensitive to cow's milk protein. If the crying does ease, you can reintroduce dairy later to confirm the connection.\n\nThis doesn't mean colic is definitely caused by milk sensitivity—colic can stem from feeding difficulties, an immature digestive system, or other factors—but it's one of the most actionable things to test. Your pediatrician can also discuss whether probiotics might help, since they may ease your baby's gut discomfort and reduce crying. Trust what you're noticing; tracking the pattern is half the detective work.","sources":"[{\"pmid\":\"41305650\",\"title\":\"Infantile Colic: When to Suspect Cow's Milk Allergy.\",\"journal\":\"Nutrients\",\"year\":\"2025\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/41305650/\",\"score\":0.83},{\"pmid\":\"30656551\",\"title\":\"Preventing and Treating Colic.\",\"journal\":\"Advances in experimental medicine and biology\",\"year\":\"2019\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/30656551/\",\"score\":0.83}]","thread_json":null,"topic":"colic-and-crying","view_count":0,"created_at":"2026-09-04T00:00:59.975Z"}
