Why Should you never Wake a Sleeping Baby

If you’re a new parent, you’ve probably heard this advice before: never wake a sleeping baby. But why is this the case? We’ll explore the reasons behind this age-old piece of advice and explain why it’s important to let your baby sleep uninterrupted. The article explains why it’s important not to wake a sleeping baby. It highlights the importance of sleep for babies, including how it supports their physical and mental development, strengthens their immune system, and regulates their appetite.

The Importance of Sleep for Babies

Sleep is essential for babies’ growth and development. During sleep, the body releases growth hormones that help with physical and mental development. Sleep also plays a vital role in strengthening the immune system, regulating appetite, and improving memory and learning. Babies need between 14 and 17 hours of sleep a day, depending on their age.

Why Waking a Sleeping Baby is a Bad Idea

Waking a sleeping baby can disrupt their sleep cycle and interfere with their overall sleep quality. When a baby is woken up abruptly, they may become cranky, fussy, or even sick. Interrupting a baby’s sleep can also lead to sleep deprivation, which can affect their mood, behavior, and cognitive function.

Sleep Cycles and Developmental Milestones

Babies have shorter sleep cycles than adults, which means they spend more time in the rapid eye movement (REM) stage of sleep. During this stage, the brain is highly active, and babies are more likely to dream. Interrupting a baby’s sleep during the REM stage can disrupt their dreams and affect their overall sleep quality. Babies also go through several developmental milestones during their first year, which can affect their sleep patterns. For example, around four months, babies go through a sleep regression, where they may wake up more frequently during the night. Waking a baby during this time can make it even more challenging for them to fall back asleep.

How to Help Your Baby Sleep Better

There are several things you can do to help your baby sleep better and avoid the need to wake them up. Establishing a consistent bedtime routine can help your baby develop healthy sleep habits. This can include a warm bath, a story or lullaby, and a consistent bedtime. You can also try swaddling your baby, using white noise, or creating a comfortable sleep environment. It’s also essential to pay attention to your baby’s sleep cues and put them to bed when they’re drowsy but not yet asleep. This can help them learn to fall asleep on their own and avoid the need for you to intervene.

Common Sleep-Related Concerns for Parents

As a new parent, you may have several concerns about your baby’s sleep, such as whether they’re getting enough sleep or if they’re sleeping too much. It’s important to remember that every baby is different, and there’s no one-size-fits-all solution to sleep. However, if you’re concerned about your baby’s sleep, you should talk to your pediatrician.

Why Sleep is Important for Babies

Sleep is vital for everyone, but it’s especially important for babies. Here are some reasons why:

•           Physical and Mental Development

Sleep plays a critical role in a baby’s physical and mental development. During sleep, the body releases growth hormones, which are essential for building and repairing tissues. Additionally, sleep is necessary for brain development, and it helps babies form new neural connections.

•           Strengthening Immune System

Sleep also strengthens a baby’s immune system. When a baby sleeps, their body produces cytokines, which are proteins that fight off infection, stress, and inflammation.

•           Regulating Appetite

Sleep plays a role in regulating a baby’s appetite. When a baby sleeps, their body produces hormones that control hunger and fullness. If a baby doesn’t get enough sleep, they may have difficulty regulating their appetite, which can lead to overeating and weight gain.

Negative Effects of Interrupted Sleep

Waking a sleeping baby can have negative consequences. Here are a few:

  • Disrupting Sleep Cycle

Babies have shorter sleep cycles than adults, and they spend more time in the REM stage of sleep. The REM stage is crucial for brain development, and waking a baby during this stage can disrupt their dreams and affect their overall sleep quality.

  • Affecting Mood and Behavior

Interrupted sleep can affect a baby’s mood and behavior. They may be cranky, irritable, and have difficulty focusing.

  • Causing Sleep Deprivation

Waking a baby can cause sleep deprivation, which can have long-term effects on their health. Sleep deprivation can lead to a weakened immune system, obesity, and other health problems.


In conclusion, waking a sleeping baby can have negative consequences for both you and your child. Sleep is crucial for babies’ physical and mental development, and disrupting their sleep cycles can have lasting effects. Instead of waking a sleeping baby, try to maximize your time with them in other ways, and establish healthy sleep patterns that benefit everyone.
