My baby just turned 4 months and their sleep suddenly fell apart—how do I know if this is regression?

Sleep regression is common in 4-month-old babies and typically shows itself with these signs: A baby who previously slept well suddenly wakes frequently at night, has trouble falling asleep, and daytime naps shorten or disappear. There may be increased fussiness and more demand for nursing or bottle. All of this signals your baby is moving into a new stage of brain development—at 4 months, their circadian rhythm (biological clock) matures and their sleep cycles become more adult-like. You can tell it's real regression when within a few weeks things improve—3-4 weeks after it starts, if things are calmer, it was normal developmental progress. If waking continues past 4 weeks, if your baby struggles to breathe, or if there's fever along with the restlessness, I'd recommend checking with your pediatrician.
