5 Month Sleep Regression – Causes and Signs You Should Know

Parenting is a beautiful journey, filled with many joys and new experiences. However, it also comes with its fair share of challenges, one of which is dealing with a baby’s sleep pattern changes. One particular phase that can be difficult for many parents to handle is the “five month sleep regression”. This term might seem alarming, especially if you’re a new parent, but understanding what it is and how to navigate it can significantly ease your worries.

What Is The 5 Month Sleep Regression?

Sleep regression refers to a period when a baby who has been sleeping well suddenly starts waking up frequently during the night and has shorter naps during the day. The “5 month old sleep regression” specifically refers to this phase when it happens around the baby’s fifth month. Babies go through several sleep regressions in the first two years of their life. While each baby is unique and may not follow a strict timeline, the most common sleep regression periods occur around 4 months, 8-10 months, and 18 months to 2 years of age.

Can Sleep Regression Happen At 5 Month?

Yes, sleep regression can happen at five months, although it’s important to note that not all babies will experience it. Some may go through this phase earlier, at three or four months, while others might experience it later. However, the five-month mark is often a time of significant developmental changes for your baby. These changes can disrupt their previously established sleeping patterns, leading to what is referred to as “five month old sleep regression”.

What Are the Causes of 5 Month Sleep Regression?

Several factors can contribute to the occurrence of a 5 month sleep regression:

1. Physical Growth: Rapid growth and physical development can cause discomfort and disrupt a baby’s sleep. Teething, for instance, can start around this age and might cause sleep interruptions due to discomfort.

2. Developmental Milestones: At around five months, babies become more aware of their surroundings and start developing abilities like rolling over, sitting up, and maybe even starting to crawl. These exciting developmental leaps can cause them to wake more frequently.

3. Changes in Sleep Cycle: As babies grow, their sleep patterns begin to resemble those of adults. This means they start cycling between deep and light sleep. This can cause them to wake up more frequently, particularly if they haven’t yet learned how to self-soothe and fall back to sleep independently.

4. Separation Anxiety: Around this age, babies begin to understand object permanence – the concept that things still exist even when they’re out of sight. This can lead to separation anxiety, especially when they wake up and find you’re not there.

5. Changes in Routine or Environment: Any major changes in a baby’s routine or environment can also lead to disruptions in their sleep. This could be anything from travelling to starting daycare or moving to a new home.

Signs of 5 Month Sleep Regression

Identifying a sleep regression can be a bit tricky, as it can sometimes be confused with other issues like illness or teething. However, here are six signs you can look out for:

1. Frequent Night Waking: If your baby, who once slept soundly through the night, starts waking up frequently, it could be a sign of sleep regression.

2. Resisting Naptime: Difficulty falling asleep for naps, short naps, or skipping naps altogether are other signs.

3. Increased Fussiness: A baby undergoing sleep regression might be more irritable or fussy, especially during the times when they should be sleeping.

4. Changes in Appetite: Some babies might eat more due to increased periods of wakefulness. Others might have  descreased appetite.

5. Clinginess: Due to potential separation anxiety, babies might become more clingy during a sleep regression.

6. Practicing New Skills: If your baby is using their wake time to practice new skills like rolling over or sitting up, they’re likely experiencing a sleep regression.

How Long Does 5 Month Sleep Regression Last?

The duration of a sleep regression can vary greatly from one baby to another. Typically, sleep regression periods last between two to six weeks. Remember, this phase is a temporary one, although it may not feel like it when you’re in the midst of it!

How Can You Manage 5 Month Sleep Regression In Your Baby?

How Can You Manage 5 Month Sleep Regression

While sleep regression can be challenging, there are strategies you can use to help your baby through this phase:

1. Establish a Sleep Routine

A consistent bedtime routine can signal to your baby that it’s time to sleep. This routine can include activities such as bathing, reading a book, or singing lullabies.

2. Encourage Independent Sleeping

Gradually teach your baby to fall asleep on their own. This can help them self-soothe and go back to sleep if they wake up during the night.

3. Make the Environment Sleep-Friendly

Ensure the baby’s room is dark, quiet, and at a comfortable temperature. Using a white noise machine can also help promote better sleep.

4. Feed Your Baby Before Sleep

A full tummy can help your baby sleep longer stretches. However, avoid creating a sleep association where your baby needs to feed to fall asleep.

5. Offer Comfort

If your baby is experiencing separation anxiety, offer comfort but try to avoid creating new sleep associations or habits that you’ll have to break later.

6. Be Patient

Remember, this phase is temporary and part of your baby’s natural development. Be patient with your baby and yourself.

7. Take Care of Yourself

Parenting a baby going through sleep regression can be exhausting. Don’t forget to take care of your own needs and rest when you can.

8. Seek Professional Advice

If you’re struggling to manage your baby’s sleep regression, don’t hesitate to seek advice from a paediatrician or a sleep consultant.

When to Call A Doctor?

While the 5 month sleep regression is usually a normal part of a baby’s development, you should reach out to a healthcare professional if you notice any of the following:

  • Your baby is excessively irritable and nothing seems to soothe them.

  • There’s a drastic change in their feeding habits or weight.

  • Your baby has difficulty breathing, high fever, or shows signs of illness.

  • Sleep problems persist beyond six weeks or are causing significant distress.


1. How Much Should 5 Month Old Baby Sleep?

At five months, a baby typically needs about 12 to 15 hours of sleep in a 24-hour period. This usually includes two to three daytime naps totalling three to four hours, with the rest of the sleep occurring during the night.

2. How I Can Get My 5 Month Old To Sleep Through The Night?

Establishing a consistent bedtime routine and encouraging independent sleeping can help your 5 month old sleep through the night. Additionally, making sure they’re getting enough to eat during the day and the room conditions are optimal for sleep can also help. Remember, every baby is different, and what works for one may not work for another. If you’re struggling, don’t hesitate to seek professional advice.

In conclusion, while dealing with a five month old sleep regression can be a challenging time for parents, understanding its causes and signs, and knowing how to navigate through it, can make this phase more manageable. Remember, it’s a temporary stage in your baby’s development and a sign that they’re growing and learning new skills. With patience, consistency, and a few helpful strategies, both you and your baby will be able to get the rest you need.
