13 Month Sleep Regression – Causes, Signs & How To Deal With It

As parents, we eagerly anticipate each milestone in our child’s life, yet some prove more challenging. The 13-month sleep regression is a developmental phase that can feel like a backwards step. During this time, toddlers may experience disruptions in their sleep patterns, leading to nighttime awakenings, difficulty falling asleep, and changes in nap schedules. This phase can be challenging for both the child and the parents, as it often involves increased restlessness and fussiness. This article offers insight into this phenomenon, discussing its causes, signs, duration, and effective management strategies.

What Is the 13-Month Sleep Regression?

At around 13 months, you may notice a sudden change in your child’s sleep patterns. The 13-month regression can cause your previously good sleeper to have frequent night awakenings, reduced nap times, or even outright resistance to bedtime. This phase is known as “sleep regression at 13 months”, and although it can be exasperating, it is a perfectly normal part of your child’s development.

What Are the Causes of 13-Month-Old Sleep Regression?

Understanding the causes behind the 13-month-old sleep regression can help manage expectations and formulate a response.

1. Developmental Milestones

Many children reach significant physical milestones around 13 months, such as walking or learning new motor skills. These advancements can excite your child, causing them to resist sleep in favour of practising their new abilities.

2. Cognitive Development

The 13th month is also a time of substantial cognitive growth. Babies are developing a stronger sense of object permanence and beginning to understand cause-and-effect relationships, which can lead to increased wakefulness or restlessness during sleep.

3. Teething

The arrival of new molars around this time can cause discomfort and disrupt sleep. When your baby is  teething, it may lead to more frequent nighttime awakenings and trouble returning to sleep.

4. Separation Anxiety

As babies develop a stronger understanding of their world, they can begin to experience separation anxiety. This anxiety can cause them to resist bedtime or nap time when they understand it means being apart from their parents or caregivers.

5. Changes in Daily Routine

Any disruption or change to a 13-month-old’s daily routine, like a family vacation or a change in daycare, could trigger sleep regression. Consistency provides comfort to young children, and when this is disrupted, it may affect their sleep patterns.

6. Growth Spurt

Babies often experience growth spurts around this age, leading to increased hunger and, subsequently, more frequent nighttime awakenings.

7. Increased Environmental Awareness

As babies mature, they become more aware of their surroundings, making them more sensitive to noise, light, and other environmental factors that may disrupt their sleep.

8. Transition From Two Naps to One

Many 13-month-olds are transitioning from two daily naps to just one. This significant change in their sleep schedule can cause temporary disruption until they adjust to the new routine.

Signs of Sleep Regression at 13 Months

Recognising the signs of sleep regression in 13-month-olds can help you tackle the problem effectively.

1. Frequent Night Awakenings

Your baby might start waking up several times at night despite previous habits (5).

2. Resistance to Bedtime

Your baby may protest or resist when it’s time to sleep (4).

3. Shorter Naps

Nap duration may suddenly decrease.

4. Changes in Appetite

There might be noticeable changes in your baby’s eating habits.

5. Mood Swings

Your baby might appear cranky or unusually irritable.

6. Excessive Clinginess

Your baby might demonstrate increased attachment or a need for comfort.

7. Increased Restlessness

There might be more tossing and turning during sleep.

8. Frequent Crying

You may notice an uptick in crying or fussiness, especially around sleep times (2).

How Long Does a 13-Month Sleep Regression Last?

Typically, sleep regression at 13 months can last between two and six weeks (3). It’s a temporary phase; your little one will return to regular sleep habits with time and patience.

How Can You Manage 13-Month-Old Sleep Regression in Your Baby?

Addressing this challenging phase involves understanding your baby’s needs and providing a supportive environment.

1. Maintain a Consistent Routine

Keeping a steady bedtime and nap routine can provide a sense of security (1).

2. Create a Soothing Sleep Environment

A calm, quiet, and dimly lit room can promote better sleep.

3. Allow for Self-Soothing

Encourage your baby to comfort themselves, which can help them get back to sleep without your intervention.

4. Address Physical Discomfort

If teething is an issue, provide appropriate pain relief.

5. Gradual Nap Transition

If shifting from two naps to one, gradually transition to minimise disruption.

6. Offer Reassurance

If separation anxiety is a cause, offer comfort and reassurance at bedtime.

7. Provide Healthy Snacks

If hunger wakes your baby, try providing a healthy snack before bedtime.

8. Be Patient

Remember, this is a temporary phase. Your patience, love, and consistency can make a significant difference.

9. Limit Overstimulation Before Bed

Avoid active play or screen time close to bedtime, as it can make it harder for your baby to wind down.

10. Use Comfort Objects

A favourite blanket or soft toy can provide security and help your baby settle more easily.

When to Call a Doctor

The 13-month sleep regression can be challenging for both parents and babies. As your little one transitions from infancy to toddlerhood, their sleep patterns and behaviours may change significantly. While most sleep regressions are a normal part of a child’s development, there are certain situations where it’s essential to seek advice from a paediatrician. Understanding when to call a doctor can help ensure your child’s well-being and provide you with peace of mind during this potentially trying phase.

Common Signs to Watch For:

1. Extreme Sleep Disruption: Sleep regressions usually cause some sleep disturbances, but if your child consistently struggles to sleep and the issues are severe, it might be cause for concern.
2. Significant Behavioural Changes: If your child’s behaviour shifts dramatically beyond sleep disruptions and they become unusually irritable, excessively fussy, or show signs of distress that persist throughout the day, consulting a doctor is advised.
3. Physical Symptoms: Any physical symptoms such as fever, vomiting, diarrhoea, or other signs of illness during the sleep regression should be addressed promptly by a medical professional.
4. Regression Lasts Longer Than Expected: While sleep regressions can last for a few weeks if they persist for an extended period without any signs of improvement, it’s wise to seek guidance from a doctor.
5. Weight or Growth Concerns: If your child’s sleep regression is accompanied by a notable decrease in appetite, weight loss, or growth concerns, it’s crucial to involve a healthcare provider to rule out any underlying medical issues.

When to Reach Out to a Doctor:

1. Persistent Crying: If your child is inconsolable, cries excessively during the night, or struggles to calm down even during the day, contacting your paediatrician can help rule out any potential health concerns.
2. Breathing Problems: If you notice irregular breathing patterns, persistent snoring, or any signs of difficulty breathing, it’s essential to consult a doctor to assess whether there might be an underlying respiratory issue.
3. Developmental Concerns: If your child experiences a significant regression in their developmental milestones alongside the sleep regression, such as loss of language skills or motor functions, it’s crucial to seek medical advice to ensure proper development.
4. Worsening of Preexisting Conditions: If your child has any preexisting medical conditions, such as asthma, allergies, or other chronic health issues, and you notice their symptoms worsening during the sleep regression, contact their healthcare provider for guidance.
5. Parental Instinct: Trust your parental instincts. If something about your child’s behaviour or health feels off to you, don’t hesitate to contact a medical professional for reassurance.

FAQs

1. Can overly long naps make nighttime sleep worse?

Surprisingly, yes. If your baby naps too long during the day (especially late afternoon), it can reduce their sleep drive at bedtime, leading to resistance or frequent night wakings. Aim for balanced nap lengths and avoid naps ending too close to bedtime.

2. Could my baby be “undertired” instead of overtired?

While overtiredness is a common issue, some babies fight sleep because they haven’t had enough awake time between naps. At 13 months, aim for 4–5 hours of wake time before bedtime to build enough sleep pressure.

The 13-month sleep regression can be challenging for parents and babies. By understanding the causes, recognising the signs, and employing effective strategies, you can help your child navigate through this period more comfortably. Remember, each child is unique, and what works for one may not work for another. Stay patient, consult your paediatrician if needed, and before you know it, you and your little one will return to peaceful nights.
