Sleep concerns affect nearly every family at some point. When it comes to sleep scheduling for twins, here is what the guidelines recommend.
The short answer
Getting twins on a synchronized sleep schedule is one of the most sought-after goals for parents of multiples - and one of the most challenging. The good news is that most twins can learn to sleep on a similar schedule with patience and consistency. It is also normal for twins to have different sleep temperaments, and flexibility is key.
Key takeaways
- Getting twins on a synchronized sleep schedule is one of the most sought-after goals for parents of multiples - and one of the most challenging. The good news is that most twins can learn to sleep on a similar schedule with patience and consistency. It is also normal for twins to have different sleep temperaments, and flexibility is key.
- Usually normal when: One twin is a "better sleeper" than the other - sleep temperament varies even between identical twins
- Call your doctor if: Either twin has an episode of paused breathing lasting more than 20 seconds, turns blue or pale, or becomes limp during sleep - call 911 immediately
- Varies by age — see the age-by-age breakdown below
“To reduce the risk of sleep-related infant deaths, the AAP recommends that infants sleep on their backs, on a firm, flat surface, without any soft bedding.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH guidelines, getting twins on a synchronized sleep schedule is one of the most sought-after goals for parents of multiples - and one of the most challenging. The good news is that most twins can learn to sleep on a similar schedule with patience and consistency. It is also normal for twins to have different sleep temperaments, and flexibility is key. At 0-3 months, newborn twins sleep in short bursts of 2-4 hours around the clock. Many parents find it helpful to wake the second twin for a feeding when the first wakes, which gradually synchronizes their schedules. Room-sharing is recommended by the AAP, but each twin should have their own separate sleep surface. Twins are often surprisingly good at sleeping through each other's crying, but if one consistently wakes the other, a temporary room separation during the adjustment period is reasonable. It is generally considered normal when one twin is a "better sleeper" than the other - sleep temperament varies even between identical twins. However, you should contact your pediatrician promptly if either twin has an episode of paused breathing lasting more than 20 seconds, turns blue or pale, or becomes limp during sleep - call 911 immediately.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Newborn twins sleep in short bursts of 2-4 hours around the clock. Many parents find it helpful to wake the second twin for a feeding when the first wakes, which gradually synchronizes their schedules. Room-sharing is recommended by the AAP, but each twin should have their own separate sleep surface. Twins are often surprisingly good at sleeping through each other's crying, but if one consistently wakes the other, a temporary room separation during the adjustment period is reasonable.
3-6 months
This is often when parents begin to see longer nighttime stretches and more predictable nap patterns. Working toward a consistent bedtime routine for both babies - even if the timing of individual steps varies slightly - helps signal sleep time. If one twin is sleeping through the night while the other is not, avoid comparing them. Each baby's sleep maturity develops on its own timeline.
6-12 months
By six months, many twins can be on a fairly synchronized schedule with two to three naps during the day and a longer stretch at night. If you choose to sleep train, you can train both twins at the same time - research suggests twins generally adjust to each other's crying within a few nights. Consistent wake times and nap times are the most powerful tools for keeping twins in sync.
12-24 months
As twins transition from two naps to one, they may not make this shift at exactly the same time. One twin may need the morning nap dropped a few weeks before the other. During transitions, some flexibility is needed - the goal is to get them back on the same schedule once both have adjusted. Toddler twins often do well sharing a room, and their shared bedtime routine can become a comforting ritual for both.
What to Tell Your Pediatrician
- Describe when you first noticed sleep scheduling for twins and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if one twin consistently snores, gasps, or pauses breathing during sleep - this may indicate obstructive sleep apnea.
- Mention if one twin is sleeping significantly less than expected for their age and seems overtired or irritable during the day.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- One twin is a "better sleeper" than the other - sleep temperament varies even between identical twins
- Your twins' schedules are not perfectly aligned, especially in the first few months
- One twin wakes the other occasionally - most twins learn to sleep through their sibling's noise surprisingly quickly
- You feel exhausted and like you never get a break - sleep deprivation with multiples is intense and real
- One twin consistently snores, gasps, or pauses breathing during sleep - this may indicate obstructive sleep apnea
- One twin is sleeping significantly less than expected for their age and seems overtired or irritable during the day
- You are so sleep-deprived that you feel unsafe driving, caring for your babies, or functioning during the day
- One twin has frequent night wakings well beyond what is expected for their age and nothing seems to help
- Either twin has an episode of paused breathing lasting more than 20 seconds, turns blue or pale, or becomes limp during sleep - call 911 immediately
- You are so exhausted that you are falling asleep while holding or feeding a baby - this is a safety emergency and you need immediate help from a partner, family member, or friend
What You Can Do at Home
- Keep track of when you notice sleep scheduling for twins — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that one twin is a "better sleeper" than the other - sleep temperament varies even between identical twins — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Maintain a consistent bedtime routine. Keep the sleep environment cool, dark, and quiet.
- While monitoring at home, seek immediate care if either twin has an episode of paused breathing lasting more than 20 seconds, turns blue or pale, or becomes limp during sleep - call 911 immediately.

Related Sleep Concerns
How Long Should Baby Be Awake Between Naps?
The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.
Is a Bath Before Bed Really Necessary?
A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.
How Long Should the Bedtime Routine Be?
An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.
Is My Baby's Bedtime Too Early?
For most babies over 3 months, bedtime between 6:00-8:00 PM is appropriate. A bedtime that is too early can cause early morning wakings (before 6 AM) or long periods of wakefulness in the middle of the night. However, during nap transitions or on days when naps were short, an earlier-than-usual bedtime helps prevent overtiredness.
Is My Baby's Bedtime Too Late?
For babies over 3-4 months, consistently going to bed after 8:30-9:00 PM may result in overtiredness, which paradoxically makes it harder to fall asleep and stay asleep. Cortisol rises when babies are overtired, leading to more night wakings and early mornings. Moving bedtime earlier, even by 15-30 minutes, often improves overnight sleep quality.
Is It Dangerous for My Baby to Sleep in a Car Seat?
Babies should not be left to sleep in car seats outside of the car. Car seat-related deaths are most often caused by positional asphyxia, which occurs when a baby's head falls forward, compressing the airway. While car seats are essential and safe for travel, the AAP recommends transferring your sleeping baby to a firm, flat sleep surface as soon as you reach your destination. Never use a car seat as a substitute for a crib or bassinet.
