Sleep Tossing In Infants: Why Does It Happen?

why 9 month old aby tosses in sleep

A 9-month-old baby's sleep cycle lasts only 50 minutes (with 50% in REM) compared to an adult's 90-120 minutes (with 20-25% in REM). This shorter cycle and frequent REM phase cause restlessness in babies, leading to tossing and turning in sleep. While this is normal, it can be addressed by establishing an age-appropriate sleep schedule and a bedtime routine. Additionally, reducing screen time and stimulants before bed can help. If your baby wakes up tired and grumpy, it may indicate a sleep disorder or underlying issue, and you should consult a healthcare provider.

Separation anxiety

There are many reasons why a 9-month-old baby may toss and turn in their sleep. One predominant theory is that they are undergoing a developmental change or leap. Nine-month-olds are achieving major physical and emotional milestones, such as learning to crawl, scoot, stand up, and sit. This can be both exhausting and exciting for the baby, who may want to practice these new skills even in their crib.

Another reason for sleep disturbances could be separation anxiety. Separation anxiety is a normal part of development in babies and toddlers, marking a shift in their understanding of themselves in relation to caregivers. It usually begins around the time infants start crawling or walking, as this is the first time they can physically distance themselves from their parents. When children realize they are separate from their caregivers, it can provoke anxiety and may lead to sleep challenges.

Sleep regression at 9 months is also common and can cause a peak in separation anxiety. During this regression, your baby can suddenly become clingy at naps and bedtime, wanting you to stay with them as they fall asleep. This can be short-lived, around a week or two, if you maintain consistent sleep schedules and bedtime routines, but it can also last longer.

  • Respond to your child's separation anxiety with understanding and empathy. It is important to help instill confidence in their ability to be away from you for periods of time.
  • Include extra cuddles and kisses during the day and in their bedtime routine.
  • Keep bedtime as normal as possible, as consistency is comforting to children.
  • A comfort object (also called a "transitional object" or "lovey") can help your baby feel safe and secure. Children often pick their own comfort object, such as a blanket or soft toy, and seek emotional comfort from it.
  • If your child is waking up frequently overnight, handle it with a loving and consistent approach. Offer comfort and reassurance through patting and soothing.
  • Be mindful that any big change in your baby's life can also trigger separation anxiety. This can include changes in their routine, such as a new child care provider.

Developmental milestones

A 9-month-old baby tossing and turning in their sleep could be a result of several factors related to their developmental milestones.

Firstly, 9-month-olds are typically curious and eager to explore their surroundings, which can make it challenging for them to settle down and fall asleep. They are also learning new skills, such as crawling, pulling up to stand, and even walking, which can be both exciting and exhausting. This surge of new developments can lead to what is commonly known as "sleep regression," where a baby who previously slept well suddenly experiences difficulties falling asleep, wakes up frequently during the night, or struggles with naps.

Secondly, at this age, babies start to develop separation anxiety as they begin to understand object permanence. They realize that even if something is out of sight, it still exists, and this awareness can cause distress when they cannot see their caregivers. This emotional milestone can disrupt their sleep patterns and cause them to wake up frequently.

Additionally, linguistic development plays a role in sleep patterns. Nine-month-olds are absorbing sounds and processing language, and these changes can impact their sleep until they adjust to their new skills and routines. Teething pain can also be a factor in sleep disturbances, as it tends to be more bothersome at night when lying down.

Furthermore, it's important to ensure that your baby is getting adequate nutrition. As you introduce solid foods, continue providing breast milk or formula, as it still accounts for a significant portion of their daily calorie intake. Skimping on milk can lead to a fussy baby who wakes up hungry at night.

Lastly, maintaining a consistent bedtime routine is crucial. A predictable routine helps your baby settle into a successful pattern of nighttime sleep. If you notice persistent restlessness and daytime fatigue, it's important to discuss this with your healthcare provider to rule out any underlying issues.

Overstimulation

A 9-month-old baby tossing in their sleep could be due to overstimulation. Babies can easily become overstimulated, which can lead to an overtired baby who lacks sleep. Overstimulation can be caused by a bright, busy household, screens, beeping toys, or crying. It is important to avoid stimulating activities at least an hour before bedtime. Creating a peaceful sleep environment can help calm a baby and reduce overstimulation. This can include adjusting the temperature and lighting, limiting the number of people in the room, and using a sound machine to create soothing noises.

Maintaining a consistent bedtime routine is crucial for a baby's sleep. A predictable routine can help a baby fall asleep more easily and reduce restlessness. Any changes to the routine, such as a vacation or a different sleep environment, can disrupt their sleep. It is beneficial to recreate their familiar bedtime routine as much as possible when away from home.

Additionally, sleep regression can occur at 8-10 months and cause temporary disruptions in a baby's sleep. During this time, babies are learning new skills and experiencing developmental milestones, which can impact their sleep. Separation anxiety, teething, and hitting milestones like crawling or walking can also contribute to sleep disturbances.

If a baby is overtired, it is important to look for signs of drowsiness, such as yawning, thumb-sucking, or fussing, and create a calm environment to help them relax and prepare for sleep. A weighted sleep sack or swaddle can provide comfort and reduce anxiety, mimicking the feeling of a human hug.

If a baby continues to wake up tired and cranky despite appearing to get enough sleep, it is recommended to discuss this with a healthcare provider to rule out any underlying issues or sleep disorders.

Teething

The symptoms of teething can vary between babies, but some common signs to look out for include drooling, biting, and gnawing. Excessive drooling can cause a rash around the mouth, cheeks, chin, and neck area. Teething can also stimulate a cough or gag reflex due to the extra saliva produced. Additionally, teething babies may experience low-grade fevers, with body temperatures ranging from 98 to 100 degrees Fahrenheit. It is important to monitor the baby's fever, as a higher fever may indicate an illness rather than teething.

To alleviate teething pain, you can offer your baby chilled or frozen teething rings, chew beads, or commercially bought teething toys. You can also provide them with frozen fruit and vegetable popsicles or teething biscuits, although these may not be very nutritious and contain added sugar and salt. A small dose of children's pain relievers, such as acetaminophen or ibuprofen for babies over 6 months old, may also help manage the pain. It is important to consult your doctor before giving any medication to your baby and to follow their instructions for dosage.

While teething typically begins around 6 months of age, it is not uncommon for some babies to start teething later, even after 9 months. The timing and order of tooth eruption can vary, but generally, the lower front teeth come in first, followed by the top front teeth, and then the teeth beside the upper front teeth.

Causes of Sleep Regression

The primary cause of sleep regression among 9-month-old babies is the multitude of exciting developmental milestones they are reaching. These include physical achievements like crawling, pulling up to stand, or even taking their first steps. The excitement and exhaustion associated with these new skills can make it challenging for babies to settle down and sleep peacefully.

Additionally, 9-month-olds are undergoing significant cognitive and emotional developments. They are learning about object permanence, which can trigger separation anxiety. This awareness of their caregiver's absence can make them fussier and more clingy, impacting their sleep patterns.

Furthermore, linguistic developments, such as babbling, imitating sounds, and processing language, can also play a role in sleep regression. The stimulation from absorbing new sounds and words may keep babies awake and disrupt their sleep.

Strategies to Manage Sleep Regression

  • Maintain a consistent daily routine: Establish a predictable schedule for your baby, including a bedtime routine that promotes sleep. Consistency is key, but it's essential to remain flexible and adapt to your baby's evolving needs.
  • Create a soothing sleep environment: Ensure the bedroom is quiet, dark, and comfortable. Use white noise to block out external disturbances, such as noisy traffic, and to help babies ignore internal discomforts, like teething pain.
  • Address any external factors: Evaluate and address potential disruptions to your baby's sleep, such as itchy pyjamas, bright lights, or cold symptoms.
  • Adjust bedtime: If your baby seems well-rested and fights sleep at their current bedtime, consider gradually moving it 15 minutes later. This can help synchronise their sleep schedule with their natural sleep cues.
  • Continue offering milk: Ensure your baby is getting adequate breastmilk or formula during the day. Skimping on milk can lead to hunger at night, causing them to pop awake.
  • Transition to two naps: Most 9-month-olds transition from three to two naps a day. If your baby is still taking three naps, consider transitioning to encourage longer and more consolidated sleep.
  • Wind-down period: Establish a pre-nap wind-down routine similar to their bedtime routine. This helps signal to your baby that it's time to relax and prepare for sleep.

Remember, sleep regression is a normal and temporary phase in your baby's development. By understanding the underlying causes and implementing consistent strategies, you can help your little one navigate this challenging period and return to restful sleep.
