At 13 months, many toddlers still need multiple naps, and the timing of those naps is often driven by how much wake time they can handle before fatigue builds up.\n\nTwo hours of wakefulness may be closer to your toddler's natural sleep window right now, which is why the nap comes easily. By three hours, they may have hit a point of overtiredness rather than readiness—a paradoxical state where fatigue actually makes it harder to fall asleep, not easier. Overtired toddlers often show more resistance and take longer to settle. This pattern typically shifts as they grow; most toddlers gradually extend their wake windows over time as their sleep capacity develops.\n\nThe research suggests that consistent naps still matter for your toddler's developing brain, so honoring their natural rhythm rather than pushing toward a longer wake window is generally the gentler approach. If three-hour stretches feel necessary for your schedule, you might watch for signs of overtiredness building during that third hour and adjust accordingly rather than aiming for a hard time cutoff.","sources":"[{\"pmid\":\"27812555\",\"title\":\"Sleep Physiology in Toddlers: Effects of Missing a Nap on Subsequent Night Sleep.\",\"journal\":\"Neurobiology of sleep and circadian rhythms\",\"year\":\"2016\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/27812555/\",\"score\":0.76}]","thread_json":null,"topic":"nap-schedules","view_count":0,"created_at":"2026-10-17T20:01:01.883Z"}
