At 10 months, many parents find themselves wondering why their baby is suddenly struggling with sleep, despite having previously established a routine. This phase can be attributed to several developmental milestones, such as separation anxiety, teething discomfort, or the onset of more complex cognitive and motor skills, which can disrupt sleep patterns. Additionally, babies at this age may be experiencing sleep regressions, where they temporarily revert to earlier sleep habits, or they might be going through a growth spurt that increases their nighttime awakenings. Understanding these factors and adjusting sleep strategies, such as maintaining a consistent bedtime routine and ensuring a soothing sleep environment, can help address these challenges and improve sleep for both baby and parents.

What You'll Learn

Sleep Regression Causes
At 10 months, your baby’s sleep patterns may suddenly shift, leaving you puzzled and exhausted. This disruption is often attributed to sleep regression, a phase where a previously good sleeper starts waking frequently or resisting bedtime. Understanding the causes can help you navigate this challenging period with patience and strategy.
Developmental Milestones: The Double-Edged Sword
Sleep regression at 10 months often coincides with major developmental leaps. Your baby might be mastering crawling, pulling to stand, or even saying their first words. These advancements are exciting but mentally stimulating, making it harder for them to "shut off" at bedtime. For example, a baby who’s learned to crawl may wake up repeatedly to practice this new skill instead of sleeping. To mitigate this, create a predictable bedtime routine that includes calming activities like a warm bath or reading a book. Avoid overstimulation before bed by limiting screen time and vigorous play at least an hour before sleep.
Separation Anxiety: The Silent Sleep Thief
Around 10 months, many babies experience heightened separation anxiety, which can disrupt sleep. They may cry or fuss when left alone in the crib because they’re more aware of your absence. This anxiety can lead to frequent night wakings or difficulty settling down. To address this, respond consistently but briefly to their cries, reassuring them without prolonging the interaction. Gradually lengthen the time before you check on them to encourage self-soothing. A lovey or soft toy can also provide comfort during this phase.
Teething Troubles: Pain That Keeps Them Awake
Teething often peaks between 9 and 12 months, and the discomfort can interfere with sleep. Symptoms like gum tenderness, drooling, and irritability may make it hard for your baby to settle. To alleviate pain, offer a cold teething ring or a damp washcloth to chew on before bed. Over-the-counter pain relievers like infant acetaminophen (follow the dosage instructions for their age and weight) can also help, but consult your pediatrician first. Keep bedtime calm and soothing to counteract the discomfort.
Routine Disruptions: Consistency is Key
Changes in your baby’s routine—whether due to travel, illness, or a new caregiver—can trigger sleep regression. At 10 months, babies thrive on predictability, and even small disruptions can throw off their sleep patterns. Reestablish a consistent bedtime routine as soon as possible, even if it means temporarily simplifying it. For instance, if you’ve been away on vacation, reintroduce the familiar bedtime story or lullaby they’re used to. Stick to regular nap and bedtime schedules to help their internal clock reset.
Hunger or Discomfort: Addressing Physical Needs
As your baby becomes more active, their caloric needs increase, and they may wake up hungry during the night. Ensure their last feeding includes nutrient-dense foods like oatmeal, yogurt, or avocado to keep them fuller longer. Additionally, check for discomfort from factors like room temperature (aim for 68–72°F) or tight clothing. A quick nighttime diaper change or adjusting their sleep environment can sometimes resolve sudden wakefulness.
Sleep regression at 10 months is temporary, but understanding its causes empowers you to respond effectively. By addressing developmental, emotional, and physical factors, you can help your baby—and yourself—get the rest you need.

Establishing Consistent Bedtime Routine
At 10 months, your baby’s sleep patterns may shift due to developmental milestones like crawling, standing, or teething, making bedtime a battleground. Establishing a consistent bedtime routine becomes your anchor in this turbulent phase, signaling to your baby that sleep is near and creating a predictable rhythm their growing brain craves. Start by setting a firm bedtime between 7:00 and 8:00 PM, as overtired babies often struggle more with settling. Consistency is key—even on weekends or during travel—to reinforce the routine’s effectiveness.
A successful bedtime routine should last 20–30 minutes and include calming activities like a warm bath, a gentle massage with baby-safe lotion, and reading a short, quiet book. Avoid overstimulation by dimming lights and turning off screens at least an hour before bedtime, as blue light disrupts melatonin production. Incorporate a transitional object, like a soft lovey or pacifier, to provide comfort as your baby learns to self-soothe. Remember, the goal is to create a sequence of events that your baby associates with sleep, not to introduce new toys or games that might excite them.
While consistency is crucial, flexibility is equally important. If your baby resists a particular step, like the bath, temporarily replace it with a quieter activity, such as singing a lullaby. Observe their cues—if they’re rubbing their eyes or fussing, it’s a sign the routine should begin sooner. Gradually, reintroduce the original steps as they adjust. Avoid rushing the routine; babies at this age thrive on predictability, and a hurried process can undermine its calming effect.
One common pitfall is allowing the routine to become a crutch for parental involvement. Aim to end the routine with your baby drowsy but awake, placed in their crib, to encourage independent sleep. If they cry, wait a few minutes before responding, gradually increasing the interval to teach self-soothing. Consistency in your response is vital—inconsistency can confuse your baby and prolong sleep struggles. Over time, this approach fosters better sleep habits and reduces nighttime awakenings.
Finally, track your progress. Keep a sleep log for a week to identify patterns and adjust the routine as needed. Note bedtime, wake-up time, and any nighttime awakenings. Small tweaks, like moving bedtime 15 minutes earlier or adding a white noise machine, can make a significant difference. Establishing a consistent bedtime routine isn’t a quick fix, but with patience and persistence, it becomes a powerful tool to help your 10-month-old—and you—get the rest you need.

Addressing Teething Discomfort
Teething often disrupts sleep in 10-month-olds, as the pressure from emerging molars irritates gums, causing pain and discomfort. Unlike earlier teething phases, molar eruption can be more intense due to the larger size of these teeth. Recognizing symptoms like excessive drooling, gum swelling, and irritability helps pinpoint teething as the culprit. Addressing this discomfort directly can significantly improve your baby’s sleep quality.
To alleviate teething pain, start with safe, age-appropriate remedies. Offer a firm rubber teething ring chilled (not frozen) to numb sore gums. Avoid liquid-filled teethers, which can break and pose a choking hazard. Massaging your baby’s gums with a clean finger or a soft, damp cloth can also provide relief. For persistent discomfort, consult your pediatrician about using a small dose of infant acetaminophen or ibuprofen (typically 1.5–5 mg/kg of acetaminophen every 4–6 hours, or 5–10 mg/kg of ibuprofen every 6–8 hours). Always follow the doctor’s guidance and avoid exceeding recommended dosages.
While over-the-counter teething gels containing benzocaine or lidocaine may seem appealing, they carry risks for infants under 2 years old, including rare but serious side effects like methemoglobinemia. Instead, opt for natural alternatives like a cold washcloth or silicone teething toys. Distraction techniques, such as gentle play or soothing music, can also help shift your baby’s focus away from discomfort, making it easier for them to settle at bedtime.
Finally, maintain consistency in your baby’s sleep routine during this challenging period. Teething discomfort can make babies more resistant to sleep, so stick to familiar cues like dimming lights, reading a book, or singing a lullaby. If nighttime awakenings occur, respond calmly and briefly to reassure your baby without fully engaging them. With patience and targeted relief strategies, you can help your teething 10-month-old return to restful sleep.

Checking for Hunger or Thirst
At 10 months, babies are growing rapidly and their nutritional needs can fluctuate, making hunger or thirst a common culprit for disrupted sleep. While it’s easy to assume a fussy baby is tired, they may simply be signaling for a drink or a snack. Breastfed babies, for instance, digest milk faster than formula-fed infants, meaning they might wake more frequently for feeds. Formula-fed babies, on the other hand, may need a small water offering if they’re thirsty, especially in warmer climates or after physical activity. Always consider whether your baby’s last meal was sufficient or if they’ve had enough fluids before assuming sleep is the issue.
To determine if hunger or thirst is the root cause, observe your baby’s cues during the day and night. A baby who consistently wakes at the same time each night might be following their natural hunger cycle, while one who fusses and reaches for a bottle or breast is likely expressing a need for nourishment. For thirst, check for dry lips or a decrease in wet diapers, though these signs are less common unless the baby is ill or dehydrated. Offering a small feed or a few sips of water (if age-appropriate) can quickly reveal whether this resolves the sleep disruption.
If you suspect hunger, adjust feeding times or portion sizes to ensure your baby is getting enough calories before bed. For breastfed babies, ensure they’re nursing for at least 10–15 minutes on each side to get the fattier, more satiating hindmilk. Formula-fed babies might benefit from a slightly larger evening bottle, but avoid overfeeding, which can cause discomfort. For solids, include iron-rich foods like pureed meats or fortified cereals, as deficiencies can disrupt sleep. Always consult a pediatrician before making significant dietary changes.
Thirst, though less common, can still interfere with sleep, especially if your baby is eating solids and not drinking enough fluids. After 6 months, babies can have small amounts of water in a sippy cup, but avoid offering more than 2–4 ounces at a time to prevent diluting their nutrient intake. If you’re concerned about dehydration, monitor urine output—pale yellow urine indicates proper hydration, while dark yellow suggests a need for more fluids. However, water should never replace breast milk or formula as the primary source of hydration at this age.
In conclusion, checking for hunger or thirst involves a combination of observation, adjustment, and caution. By ensuring your baby is well-fed and hydrated before bedtime, you can eliminate these basic needs as potential causes of sleep disruption. Keep a log of feeding and drinking times to identify patterns, and remember that every baby is unique—what works for one may not work for another. Addressing these needs proactively can lead to more restful nights for both you and your baby.

Creating a Soothing Sleep Environment
At 10 months, your baby’s sleep patterns may shift due to developmental milestones like crawling, standing, or teething, making it harder for them to settle. Creating a soothing sleep environment becomes crucial to counteract these disruptions. Start by evaluating the room’s temperature, which should ideally be between 68°F and 72°F (20°C and 22°C). A consistent, cool temperature helps regulate your baby’s body heat, promoting deeper sleep. Use a thermostat or a room thermometer to monitor this, and adjust clothing or bedding layers accordingly.
Next, consider the role of light and sound. Darkness signals melatonin production, so invest in blackout curtains or a portable blackout blind to block out any intrusive light. For noise, white noise machines or apps can mask sudden sounds that might startle your baby awake. Aim for a steady, low-frequency hum (around 50-60 decibels) to mimic the womb environment. Avoid complete silence, as it can make your baby more sensitive to unexpected noises.
The crib itself is another critical element. Ensure the mattress is firm, flat, and covered with a tight-fitting sheet. Remove all loose items like blankets, toys, or bumpers to reduce suffocation risks. Instead, use a sleep sack or wearable blanket to keep your baby warm without the hazards of loose bedding. For added comfort, introduce a single, washable lovey or soft toy after 12 months, but avoid it before then to prioritize safety.
Finally, establish a calming pre-sleep routine to signal that bedtime is approaching. This could include a warm bath, gentle massage with baby-safe oil, or quiet reading in dim light. Keep the routine consistent and under 30 minutes to avoid overstimulation. Pair this with a predictable sleep schedule, aiming for 11-14 hours of total sleep per day, including naps. Consistency in both environment and routine will help your baby recognize sleep cues, making it easier for them to settle and stay asleep.
