Why do babies wake up so often at night?
Infant sleep works differently from adult sleep. Babies move through lighter and shorter sleep cycles, which can make rest seem unpredictable. Parents may feel unsure about how to respond to these patterns.
Learning about infant sleep cycles helps reduce worry and makes care easier. With the right support, babies can develop healthy sleep habits over time. Understanding these cycles also gives parents more patience and confidence during the early months.
Let’s explore how to support them better.
Light Sleep Stage
During the light sleep stage, babies are more sensitive to their surroundings. Small sounds or changes in temperature can make them stir or wake up. Their breathing may be uneven, and you might see their eyes move under closed lids.
Since light sleep is easy to disturb, comfort is important. Top-quality bamboo sleep sacks can help regulate temperature and keep babies cozy. A calm and steady sleep space makes it easier for babies to rest during this stage.
Deep Sleep Stage
Deep sleep is when a baby’s body rests and grows the most. During this stage, their breathing is steady, and their body is still. They are less likely to wake up from noise or movement. This quiet period allows the body to release growth hormones and repair cells, which are vital for healthy development.
Parents often feel more at ease during this stage because the baby seems settled. It is a good time for parents to rest too, knowing their baby is in a calm state. Keeping the sleep space dark, cool, and quiet supports deep sleep and helps babies stay asleep longer.
Active REM Sleep
REM sleep, or rapid eye movement sleep, is when the brain is active, and dreams occur. Babies may twitch their fingers or flutter their eyelids, even though their muscles remain relaxed. This stage is important for memory and learning.
Since babies spend much of their time in REM sleep, movement during it is normal. Parents should not worry if their baby looks restless. Keeping the sleep space safe and calm supports this active stage of rest.
Brief Wake Periods
Babies often wake for short periods between sleep stages. These wake-ups can include moving, making sounds, or even opening their eyes for a few minutes. Sometimes they need feeding or comfort, while other times they settle back on their own. These periods are a natural part of their sleep cycle and not a sign of poor sleep.
For parents, it can be helpful to allow babies a moment to settle themselves. Rushing in too quickly may disrupt their chance to return to sleep. Keeping the room calm and maintaining a steady bedtime routine can reduce fussiness during these wake-ups.
Cycle Repeats Often
Baby sleep cycles are shorter than those of adults, lasting about 50 to 60 minutes. Each cycle includes light sleep, deep sleep, REM sleep, and short wake-ups. Because they repeat often, frequent waking is normal.
Knowing this helps parents understand that waking is part of growth. Over time, cycles get longer, and babies sleep for longer stretches. A steady routine and a safe sleep space make these repeating cycles easier for both the baby and the parents.
Supporting Healthy Baby Sleep
Caring for a baby’s sleep takes patience and understanding. Each stage of rest plays a role in growth and well-being.
By creating a safe and calm space, parents can make nights easier. With time, babies learn to rest for longer and more peacefully.
