Understanding Infant Sleep Regressions

What Is a Sleep Regression?

A sleep regression is a temporary phase where your baby’s sleep pattern goes haywire. You might notice more wake-ups, shorter naps, and difficulty settling down, even if they were previously sleeping well. This usually happens because of significant developmental leaps. As your baby’s brain learns new skills, sleep often takes a backseat.

Sleep regressions can also arise if your little one feels unwell, or due to changes in their environment or routine. Here are some factors that may contribute to sleep regressions:

• Having a growth spurt

• Teething pain

• Learning to roll, stand, crawl, or walk

• Language development

• Starting nursery or parents returning to work

• Separation anxiety

• Illness

• Changes in nap routine

• A desire for more independence

  
  

Sleep regressions can occur at any time, as all children develop at different rates. However, the most common ages for regressions are 4, 8, and 18 months when significant changes are happening.

The 4-Month Infant Sleep Regression

The “Welcome to Real Sleep” Regression

This regression is a big one. Around 4 months, your baby’s sleep cycle begins to mature. They start sleeping in cycles, experiencing lighter stages of sleep and more frequent transitions. As a result, they may wake more often and struggle to link sleep cycles independently.

During this period, you might notice:

• Shorter naps

• Increased night waking

• Fussiness or early rising

• Trouble settling to sleep

  
  

What Helps:

• Create a consistent bedtime routine.

• Put the baby down awake to practice self-settling.

• Monitor their awake times between naps.

  
  

The 8–10 Month Sleep Regression

The “I Just Learned to Crawl, Stand, and Wave, Why Would I Sleep?” Regression

Between 8 and 10 months, babies hit major milestones such as crawling and cruising. Their brains are busy, and they want to practice skills even at 3 AM. This period might also coincide with separation anxiety and teething.

You might notice:

• Fighting naps or bedtime

• Standing up in the crib (and not knowing how to get back down)

• Increasing separation anxiety

  
  

What Helps:

• Provide plenty of time during the day for them to practice new skills.

• Stick to your routine as closely as possible.

• Offer reassurance without creating new habits that may be hard to break later.

  
  

This phase can last a few weeks but is usually short-lived.

The 18-Month Sleep Regression

The “My Toddler Has Opinions Now” Regression

At around 18 months, toddlers start to become fiercely independent. They may experience frustration with language development, tooth discomfort from teething, and heightened separation anxiety.

During this time, you might notice:

• Refusing to go to bed

• Night waking and calling for you

• Fighting naps or skipping them entirely

• Frequent cries of “no!” during bedtime

  
  

What Helps:

• Maintain consistent boundaries during bedtime.

• Keep the bedtime routine calm and predictable.

• Offer choices when possible, such as “Do you want to wear blue pajamas or red ones?” This helps them feel a sense of control.

  
  

Coping with Sleep Regressions

Sleep regressions can be challenging, but they serve as signs that your little one is growing and developing as they should be. It’s essential to remain consistent in your approach. Here's how to help you cope:

• Stay Consistent: Keeping a consistent routine helps and reassures your baby.

• Offer Comfort: Provide comfort but try to avoid introducing new sleep habits.

• Remember You’re Not Alone: Many parents face similar issues, so don’t hesitate to reach out for support.

  
  

Final Thoughts

Navigating sleep regressions can be tough, but it's crucial to remember that they are temporary. As you provide stability, understanding, and a comforting environment, your baby will emerge from these regressions ready for restful nights ahead.

Sleep is essential for everyone, especially for developing babies. Understanding your baby’s sleep needs and patterns will ultimately support their growth and your well-being.

Stay calm and remember that these phases will pass. Through consistency and patience, you and your baby will make it through just fine.
