Crying & Fussiness: Understanding and Soothing
It is six in the evening, you have fed, burped, changed and swayed, and the crying is still going. Nothing about that hour means you are missing something obvious. Babies cry hardest in the late afternoon and evening for the first few months, and the useful question is usually not why in general but why right now.
Timing narrows it fast. Crying that starts on the changing table often tracks a cold surface, being laid flat, or dislike of the position itself. Crying that begins minutes after a feed points at swallowed air, a fast letdown, or too much too quickly, while fussing at the breast mid feed usually involves flow, latch or a baby who needs a burp before continuing. Crying in sleep is often a partial waking between cycles that ends on its own if you wait a beat before going in.
Soothing runs on the same few levers, motion, sound, sucking, warmth and a dimmer room, and sleep training methods sit on top of that as a separate decision about age, temperament and what you can live with at two in the morning. Older children trade crying for whining, which responds to different handling entirely. Two things do warrant a call rather than patience: a newborn who is unusually quiet, limp or hard to rouse, and a cry that changes character and stays inconsolable, especially alongside fever in the first months.
