If your 7-week-old is doing both, that's a shift worth investigating with your pediatrician rather than assuming it's colic alone.\n\nColic is characterized by inconsolable crying between 1–4 months, often linked to feeding issues, a developing nervous system, or gut sensitivities—but a colicky baby who's feeding well will usually gain weight normally. Weight loss or feeding refusal points to something that needs assessment: it could be a milk supply issue, a latch problem, tongue tie, a feeding aversion, or an infection. Your pediatrician can weigh your baby, check for these causes, and rule out anything that needs treatment.\n\nIf colic is part of what's happening, probiotics may help calm your baby's gut and reduce crying. But the weight loss and refusal to feed are the priority to address first—those are separate from colic and need direct attention. Get your baby checked soon so you can understand what's actually going on and get support.","sources":"[{\"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\":0.79},{\"pmid\":\"34098710\",\"title\":\"Evaluation of perceived breast milk insufficiency in mothers of infants with infantile colic: a case-control study.\",\"journal\":\"Minerva pediatrics\",\"year\":\"2022\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/34098710/\",\"score\":0.79}]","thread_json":null,"topic":"colic-and-crying","view_count":0,"created_at":"2026-10-01T23:01:05.781Z"}
