Guide notes
The 8-month sleep regression is usually a cluster of real developmental changes, not a sign that your baby has forgotten how to sleep. Around this age, separation anxiety, crawling, pulling up, object permanence, teething, illness, childcare changes, and shifting naps can all land at the same time.

Regression is a parent word, not a diagnosis. Use it as a clue to look at the whole day. If your baby is suddenly crying when you leave, practising new movement in the cot, waking after one sleep cycle, resisting the second nap, or needing more reassurance overnight, the problem might be development plus tired adults rather than one broken routine.
Your 8-month-old is also doing a lot while awake. Many babies around 8 to 9 months are babbling, looking for hidden objects, forming stronger attachments, crawling or shuffling, pulling up to stand, practising finger foods, and showing fear of strangers or separation anxiety. Those skills are useful, but they can make bedtime louder.
Nap timing often needs a review before bedtime does. Some 8-month-olds still need 3 naps on busy or early-start days, while others are moving toward 2 stronger naps. Watch the last wake window: too short can mean bedtime play, too long can mean frantic crying and false starts.
Practise skills during the day. Crawling space, supervised floor time, pulling-up practice on stable furniture, outdoor light, songs, books, peekaboo, and hidden-toy games can help the new skills belong to waking hours. Your baby may still practise at 2 am, but daytime practice gives the body more chances to learn.
A 5 to 7 day sleep chart can turn a messy week into useful information. Track wake time, naps, bedtime, night wakes, feeds, resettling attempts, illness, childcare days, and parent shifts. Bring the chart to a health professional if you are worried or if the pattern is draining the household.
