Sleep regression in 15-month-old toddlers is a common phenomenon, characterised by an interruption in their nighttime sleep and naptime schedules. While not all toddlers will experience this, those who do may exhibit symptoms such as resisting or skipping naps, increased separation anxiety, and newfound independence. The regression is often temporary, lasting a few weeks, and can be addressed by remaining consistent with sleep routines and addressing the underlying causes, such as teething or developmental milestones.

Separation anxiety
To help your toddler with separation anxiety, you can play games like Peek-a-Boo or Hide-and-Seek, which reinforce the idea that you will come back even when out of sight. Spending awake time in your toddler's room can also help them associate it with positive feelings. Practicing planned separation can also help, such as having the other parent do bedtime or having a babysitter over while you run an errand. Maintaining consistent sleep schedules and bedtime routines can help separation anxiety-related sleep disruptions pass within a week or two.
Additionally, having one-on-one time with your child, even for just 10-15 minutes, can help them adjust to big transitions or changes. It is also important to keep bedtime as normal as possible, as consistency is comforting to children. A comfort object, such as a blanket or soft toy, can also help your child feel safe and secure.

Teething
If your 15-month-old is teething, you may notice swollen gums or a white nub before the tooth appears. Once the tooth has erupted, sleep patterns should return to normal. However, it is important to maintain a consistent bedtime routine and healthy sleep habits during this time to help your child through the regression.
To help your toddler through this challenging time, it is recommended to remain consistent with your approach to sleep and provide comfort when needed. Games like Peek-a-Boo or Hide-and-Seek can help your child understand object permanence and reduce their anxiety.
While sleep regression at 15 months can be difficult, it is typically temporary and should resolve within a few weeks. Maintaining a consistent bedtime routine and addressing any physical discomfort, such as teething, can help your child get back on track with their sleep.

Developmental progressions
Sleep regressions are often tied to developmental progressions. At 14-15 months, toddlers are reaching several developmental milestones, which can impact their sleep.
Firstly, toddlers at this age are better able to understand the concept of object permanence, which can lead to increased separation anxiety. This can cause difficulties with sleep, as toddlers may cry when entering their room or when laid in their crib, or they may stand in the crib and resist sleep. Games such as Peek-a-Boo or Hide-and-Seek can help toddlers explore and understand the concept of object permanence, which may reduce their anxiety.
Secondly, 14-15-month-old toddlers are also becoming more independent and wanting to do more things by themselves. This newfound independence can cause resistance to sleep, as they may not want help from their parents or caregivers.
Thirdly, this is also a critical period for physical development. At 14-15 months, toddlers may be taking their first steps, walking independently, or even climbing on furniture or stairs. This increased physical activity and mobility can impact their sleep patterns, as they may be more tired or have different sleep needs.
Additionally, the transition from two naps to one during the day can also contribute to sleep regression at this age. While some toddlers may be ready to drop one of their naps and transition to a longer awake period, others may not be ready for this change. A consistent sleep schedule and gradual adjustments can help toddlers adjust to this transition and improve their sleep.
Finally, teething can also be a factor in sleep disruption during these months, as new teeth can cause discomfort and pain, impacting sleep patterns.

Nap transitions
A 15-month sleep regression is an interruption in the sleep schedule of a toddler that happens when they are around 15 months old. Not all toddlers will go through this phase, but those who do may start resisting or skipping naps.
If your 15-month-old is resisting naps or taking shorter ones, they may be ready for longer awake periods or a nap transition. A schedule adjustment may help get daytime sleep back on track. If your toddler is still taking two naps, consider lengthening their awake periods to between 3.5 and 4 hours before their first nap. While lengthened awake periods may help some children, others may be ready to drop their afternoon nap and follow a one-nap schedule.
The transition from two naps to one can be rocky, and your toddler may be overtired, grumpy, and weepy during this time. It is important to let your child take the lead and adjust sleep times before dropping a nap. The transition from two naps to one should be gradual, and you can do this by slowly pushing their morning nap later by 15- or 30-minute intervals every couple of days. You may also need to adjust their evening routine to accommodate for fewer daytime naps.
The typical age for the two-to-one nap transition is between 12 and 18 months, but every child is different. Some may be ready to drop their second nap as early as 14 months, while others may not be ready until around 19 months. The transition can happen over a few weeks, and there is no set timeline. Signs that your child is ready to drop a nap include having trouble falling asleep at nap time and/or bedtime. If you see these signs consistently for approximately two weeks, then it may be time to transition your toddler to one nap.

Sleep training
Sleep regression in 15-month-old toddlers can be attributed to several factors, including physical, emotional, and developmental milestones. This can manifest as a resistance to bedtime, increased fussiness during sleep transitions, multiple night wakings, shorter or skipped naps, changes in appetite, and earlier waking. While this phase is temporary and typically lasts a few days to weeks, it can be challenging for both parents and toddlers.
Pick-up, Put-down Method (Fading Method)
This technique involves staying in the room with your toddler until they fall asleep deeply, gradually giving them more space and independence. It is recommended for toddlers between 9 and 18 months old. Start by creating a soothing environment with strong white noise and sitting quietly next to their crib or bed. As your toddler adjusts, you can move further away and eventually out of the room, teaching them to fall asleep independently.
Longer and Longer Method (Ferber-style Graduated Extinction Method)
Also known as the "cry it out" method, this approach involves gradually increasing the time between checking on your toddler as they cry. Start by letting them cry for three minutes, then pop your head in briefly to reassure them. After that, wait five minutes, and if needed, repeat the process. Gradually increase the time intervals before checking in, such as waiting 10 minutes, then 15 minutes, and so on, until they fall asleep.
Kim West's Gentle Sleep Lady Shuffle
This method focuses on providing extra comfort and reassurance while helping your toddler develop self-soothing and independent sleep skills. It involves staying close to your child and adapting the pace to their needs, ensuring they feel supported. This gentle approach works with your child, allowing them to learn healthy sleep habits at a comfortable pace.
Consistent Bedtime and Nap Routine
Consistency is crucial during sleep regression. Maintaining a consistent bedtime and nap routine signals to your toddler that sleep is coming regularly. This helps them understand the expectation of sleep and can make it easier for them to settle.
Schedule Adjustment
If your toddler is struggling with daytime sleep, consider adjusting their schedule. Lengthen their awake periods before the first nap to ensure they are tired but not overtired. Some toddlers may be ready to transition from two naps to one, following a 1-nap schedule. However, every child is unique, so observe their cues and make adjustments accordingly.
Remember, sleep training methods should be tailored to your toddler's temperament and needs. Some methods may work better than others, and it's important to remain consistent and patient during this temporary phase.
