20 Month Sleep Regression – Causes, Signs and What to Do

Navigating the ebbs and flows of a toddler’s development is a journey many parents embark upon with anticipation and apprehension. Just as you think you’ve mastered one phase, a new challenge arises. One such curveball thrown amid toddlerhood is the 20-month sleep regression. While many parents have just begun to enjoy the consistent sleep patterns of their toddlers, the sudden onset of sleep disruptions can be both surprising and exhausting. In this guide, we’ll delve deep into the causes, signs, and coping strategies related to the 20-month sleep regression, equipping you with the knowledge and tips to weather this temporary storm with confidence and care.

What Is The 20 Month Sleep Regression?

The 20-month sleep regression refers to a period when a toddler, who might have previously been sleeping well, suddenly experiences disruptions in their sleep patterns. These disruptions can manifest as difficulty falling asleep, resisting naps, waking up more frequently during the night, or waking up early in the morning. It’s one of several sleep regressions that can occur in a child’s early years, with each corresponding to different developmental milestones or changes. The 20-month regression, in particular, can be challenging for both the child and the parents, as it often coincides with significant developmental leaps, changes in routine, or the onset of separation anxiety (1).

What Are the Causes of 20-Month Sleep Regression?

Numerous developmental milestones mark the intricate journey of toddlerhood. While these milestones represent growth and learning, they can sometimes lead to temporary disruptions, particularly in sleep patterns. The sleep regression in a 20-month-old can baffle many parents, especially if their child had previously been a predictable sleeper. By understanding the root causes of this sleep disruption, parents can better empathize with and support their toddlers during this challenging period. Here are the five primary causes:

1. Developmental Milestones

At around 20 months, toddlers experience a surge in cognitive, motor, and linguistic development (2). Whether mastering a new word, walking more confidently, or showing heightened curiosity, these growth spurts can lead to more active brains, making settling down harder (3).

2. 20-Month Separation Anxiety Sleep Regression

Separation anxiety peaks around this age. The realization of being separate entities from their caregivers can create anxiety. The fear of being left alone or the desire to be close to a parent can disrupt sleep, leading to the specific 20-month separation anxiety sleep regression (4).

3. Teething

By 20 months, many toddlers are getting molars, which can be painful and lead to restless nights. The discomfort and pain associated with teething can be a significant reason for disrupted sleep (5).

4. Desire for Independence

As toddlers approach the age of two, they often display a budding sense of independence. This newfound autonomy can manifest in various ways, including wanting to decide when to go to sleep or resisting bedtime routines they previously adhered to (6).

5. Changes in Daily Routine

Any alteration in a toddler’s environment, such as transitioning from two naps to one, travelling, changing daycare, or even welcoming a new sibling, can change their sleep patterns (7).

Recognizing these causes can equip parents with the insights they need to provide the necessary comfort and adjustments, ensuring the transition through this sleep regression phase is as smooth as possible.

Signs of 20-Month-Old Sleep Regression

As toddlers grow, their sleep patterns can take unexpected turns, especially during the pivotal phase of sleep regression 20 months into their lives. For parents who have gotten accustomed to a certain rhythm, these changes can be a bit of a shock. Recognizing the signs early can help parents navigate this phase more effectively. Here are the five most common signs to look out for during this sleep regression:

1. Frequent Night Wakings

A toddler who previously slept soundly through the night might suddenly begin waking up multiple times. This can be particularly challenging as they might have difficulty settling back down.

2. Resistance to Napping

Your toddler may resist their usual nap times despite showing signs of tiredness. They might take longer to fall asleep during the day or skip naps entirely (8).

3. Changes in Sleep Duration

The total amount of sleep your toddler gets in 24 hours may be reduced. They could either wake up earlier than usual in the mornings or take longer to fall asleep at night, shortening the overall sleep duration.

4. Increased Irritability

A direct consequence of disrupted sleep is a cranky and irritable demeanour. The lack of rest can affect their mood, leading to frequent tantrums or mood swings (8).

5. Difficulty Settling at Bedtime

The bedtime routine that once worked wonders might now be met with resistance. Toddlers going through this regression can take longer to fall asleep, even if they’re visibly tired (8).

Understanding these signs can be the first step towards addressing and managing the challenges brought about by sleep regression at 20 months.

How Long Does Sleep Regression at 20 Months Last?

One of the most pressing questions on parents’ minds when faced with the challenges of a disrupted sleep routine is how long this phase will last. The sleep regression in a 20-month-old is a temporary phase, but its duration can vary among toddlers.

Typically, this sleep regression lasts two to six weeks (1). However, the duration depends on various factors, such as the child’s overall health, developmental milestones, and changes in their environment or routine.

While it may seem like an eternity when you’re in the midst of it, especially with sleep-deprived nights, it’s crucial to remember that this phase is temporary. With understanding, patience, and consistent routines, most toddlers will gradually return to their regular sleeping habits. During this time, parents must provide a supportive and comforting environment to ease the transition and help their child navigate this developmental phase.

How Can You Manage 20-Month Sleep Regression In Your Baby?

Facing sleep regression can be exhausting for both parents and toddlers. Here are some coping strategies.

1. Consistency: Maintain a consistent bedtime routine. This familiar sequence can offer comfort to your child (1).

2. Comfort Items: A favourite toy or blanket can offer solace, especially when facing separation anxiety (1).

3. Positive Reinforcement: Praise your toddler when they sleep well to encourage good behaviour (1).

4. Seek Support: Discuss strategies with your paediatrician or consider joining parent support groups.
