Why Is My Baby Waking After 1 Hour? How to Stop False Starts.

Why Is My Baby Waking After 1 Hour?
If you are wondering why your baby is waking after 1 hour, you are not alone. Many babies wake 30–60 minutes after bedtime, often due to a “false start.” Baby waking after 1 hour is commonly caused by overtiredness, undertiredness, or sleep associations (like needing rocking or feeding to fall back asleep). Other reasons include short sleep cycles, teething, or discomfort.
Does it feel like no matter what you do, you can’t always stop your baby waking after 1 hour? My sleep guides provide practical, step-by-step strategies to help your baby sleep longer stretches, reduce false starts, and settle more easily. Choose your baby’s age to get started:

8 Common Causes of Baby Waking After 1 Hour
If your baby is waking after 1 hour, it’s often due to one or more of the following causes:
1. Wake windows need adjusting
Wake windows are critical to helping your baby fall asleep easily and stay asleep. Overtired babies may wake frequently at night, while undertired babies may fall asleep but struggle to stay asleep. Both can lead to baby waking after 1 hour.
2. Baby is falling asleep during bedtime feeding
Falling asleep while feeding can lead to false start bedtimes. Even if your baby is tired enough to fall asleep initially, they may not be tired enough to stay asleep, causing baby waking after 1 hour.
3. Baby is going into the crib drowsy or fully asleep
About every 40 – 50 minutes, babies transition to a new sleep cycle. If your baby goes into the crib fully asleep, they may wake at the end of a cycle feeling confused, thinking, “Hey, what’s going on? This isn’t where I fell asleep.” How to fix: Encourage independent sleep by putting your baby down drowsy but awake. This helps them learn to connect sleep cycles on their own.
4. Your baby is younger than 3 – 4 months and simply needs a later bedtime
At this age, false starts are common. Babies with a 7:00 – 8:00 pm bedtime may even treat that bedtime like a nap. This is developmentally normal. Many babies at this age just need a later bedtime, which helps to prevent your baby waking after 1 hour.
5. The day is starting too late
Even when a baby appears to be getting the recommended amount of total sleep for their age, how that sleep is distributed across the day matters just as much. For babies, meeting age-appropriate sleep needs across a 24-hour period only works when the day is structured in a way that supports night sleep. If your baby’s day starts too late, they may not build enough sleep pressure by bedtime, causing bedtime to function more like a nap and baby waking after 1 hour, often referred to as a false start. Aligning morning wake-up times, naps, and bedtime with your child’s age-appropriate sleep needs helps ensure sleep is consolidated rather than fragmented at night.

6. Developmental milestones and growth spurts
Teething, sleep regressions, learning to roll, crawl, separation anxiety or rapid growth – growth spurts can temporarily disrupt sleep.
7. Environmental factors
Noise, light, room temperature, or general discomfort can trigger early-night awakenings. Optimizing the sleep environment with a dark, quiet, and comfortably cool room can reduce baby waking after 1 hour.
8. Safe response after a false start
Even with adjustments, baby waking after 1 hour can still happen. Respond safely: replace the pacifier, rock or bounce briefly, and lay your baby back down. Feeding isn’t usually necessary unless your baby is truly hungry. Over time, teaching independent sleep and following a consistent bedtime routine reduces false starts.
HOW to Stop a Baby From Waking 1 Hour After Bedtime
If your baby is waking after 1 hour, false starts can be incredibly frustrating. While there is rarely one single fix, the steps below can significantly reduce early-night wakings and help your baby sleep longer stretches.
1. Adjust Wake Windows
Fine-tuning the final wake window before bedtime is often one of the most effective fixes for baby waking after 1 hour.
What can you do:
-
Adjust the last wake window by 15- 30 minutes earlier or later
-
Watch closely for overtired signs like meltdowns or fighting sleep
-
Look for under-tired signs such as short naps and high alertness
2. Optimise Bedtime Feeding
If your baby falls asleep during their final feed, they may struggle to stay asleep and wake shortly after bedtime.
What can you do:
-
Keep your baby awake during the last feed
-
Move the feed earlier in the bedtime routine
-
Keep lights on and white noise off during feeding
-
Feed in a different room if needed
3. Encourage Independent Sleep
Babies briefly wake between sleep cycles. If they fall asleep fully assisted, they may struggle to resettle when they stir.
What can you do:
-
Put your baby down drowsy but awake
-
Gradually reduce rocking, bouncing, or holding
-
Support your baby in learning to settle in their sleep space.
Learning independent settling can take time, especially when baby waking after 1 hour has become a pattern. If you want step-by-step guidance, my Sleep Guide by Age 0–6 Years walks you through age-appropriate routines and settling strategies, while my sleep consultancy services offer tailored support if you need one-to-one help.
4. Adjust Bedtime for Younger Babies
For babies under 3–4 months, bedtime may simply be too early.
What can you do:
-
Allow a short early evening nap if needed
-
Aim for an 9:00 – 10:00 pm bedtime for babies under 5 months
-
Gradually move bedtime earlier as your baby approaches 5 months
- Check out the 0 – 3 months guide for newborn for more guidance on age-appropriate sleep routines, optimal nap timing, and strategies to reduce early night wakings.
5. Start the Day Earlier
Late mornings can interfere with sleep pressure and contribute to baby waking after 1 hour.
What to do:
-
Wake your baby between 6:00–8:00 am
-
Ensure total daytime sleep is age-appropriate
-
Adjust bedtime to match overall awake time
6. Check the Sleep Environment
Even small environmental disruptions can trigger early wakings.
What to do:
-
Use blackout blinds to keep the room dark
-
Keep the room at a comfortable temperature
-
Use white noise to mask sudden sounds
7. Respond Calmly After a False Start
Even with adjustments, baby waking after 1 hour can still happen occasionally.
What to do:
-
Replace the dummy quickly if used
-
Rock or bounce briefly, then put your baby back down
-
Avoid feeding unless hunger is likely
-
Keep interaction minimal and quiet
8. Be Patient During Developmental Phases
Teething, rolling, crawling, or growth spurts can temporarily increase baby waking after 1 hour. These phases are normal and usually pass with time and consistency.
9. Track Progress and Adjust
Keep a simple sleep log to note when baby waking after 1 hour occurs and which changes help most. Consistency matters, and many families see improvement within one to two weeks.
To summarise, night wakings in the first year are very common and usually reflect normal sleep cycle transitions rather than a problem. Research from “Spontaneous awakenings from sleep in the first year of life” shows that brief night awakenings are a typical part of infant development, with most babies gradually learning to self-settle between sleep cycles. Encouraging independent sleep and following consistent routines can help reduce false starts and support longer stretches of rest.
