The research shows that waking 1–3 times overnight remains completely normal and common through 12 months—so while 5 is on the higher end, it falls within typical infant sleep variation at this age.\n\nWhat matters most is that your baby is getting enough total sleep: 12–16 hours per 24 hours including naps. If they're hitting that target across the day and naps, their development is on track regardless of how the sleep is broken up at night. Babies this age often have unpredictable nights—one night might be quieter, the next busier—and that's just how their sleep works right now.\n\nThe one thing to watch: if your baby consistently sleeps fewer than 10 hours total in a 24-hour period, that would be worth mentioning to your pediatrician. Otherwise, frequent night waking at 9 months is developmentally normal, even if it's wearing on you.","sources":"[{\"title\":\"Relations between infant sleep quality, physiological reactivity, and emotional reactivity to stress at 3 and 6 months.\",\"journal\":\"Infant behavior & development\",\"year\":\"2022\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/35158216/\",\"score\":0.76},{\"title\":\"Sleep characteristics and changes in sleep patterns among infants in Bhaktapur, Nepal.\",\"journal\":\"Sleep health\",\"year\":\"2024\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/38519363/\",\"score\":0.75},{\"title\":\"Sleeping through the night or through the nights?\",\"journal\":\"Sleep medicine\",\"year\":\"2020\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/33130350/\",\"score\":0.75},{\"title\":\"Uninterrupted Infant Sleep, Development, and Maternal Mood.\",\"journal\":\"Pediatrics\",\"year\":\"2018\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/30420470/\",\"score\":0.73},{\"title\":\"Reference values and changes in infant sleep-wake behaviour during the first 12 months of life: a systematic review.\",\"journal\":\"Journal of sleep research\",\"year\":\"2018\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/29356197/\",\"score\":0.73}]","view_count":1,"created_at":"2026-07-09T02:42:03.858Z"}
