The sources don't address this specific pattern, but they do point to the factors most worth examining: screen time (especially in the two hours before bed), overall bedtime consistency on weekdays, and whether something in their environment or routine has shifted recently.\n\nIf your child has always been an early sleeper naturally, temperament plays a real role. But a sudden shift to very early sleep followed by a long middle-of-the-night wake is worth exploring with your pediatrician. This could reflect overtiredness, an underlying sleep issue, hunger, or environmental factors like noise or light that wakes them in the early morning hours. Your pediatrician can help rule out any physical causes and work with you on whether adjusting bedtime, sleep environment, or daytime routine might help consolidate their sleep into longer stretches.\n\nContact your pediatrician if this pattern is new, if your child seems overtired during the day despite the total sleep hours, or if adjusting screens and routine over a week or two doesn't improve the middle-of-the-night waking.","sources":"[{\"pmid\":\"29747723\",\"title\":\"Sleep Patterns in Chinese Preschool Children: A Population-Based Study.\",\"journal\":\"Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine\",\"year\":\"2018\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/29747723/\",\"score\":0.73},{\"pmid\":\"36806406\",\"title\":\"Questionnaire survey on sleep habits of 3-year-old children in Asahikawa City: Comparison between 2005 and 2020.\",\"journal\":\"Brain & development\",\"year\":\"2023\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/36806406/\",\"score\":0.72}]","thread_json":null,"topic":"sleep-norms-by-age","view_count":0,"created_at":"2026-09-27T00:02:00.277Z"}
