How to survive the 8 to 10 month sleep regression: a practical guide for tired parents

Just when you think you've cracked sleep, your baby starts waking multiple times a night, fighting naps and refusing to settle.

If this sounds familiar, you're not alone.

The 8 to 10 month sleep regression is one of the most common sleep challenges parents experience. The good news? It's usually temporary and often linked to exciting developmental progress.

Here's what's happening, why it happens and how you can support your baby through it.

What is the 8 to 10 month sleep regression?

A sleep regression is a period when a baby who was previously sleeping well suddenly starts:

• Waking more frequently overnight
• Taking shorter naps
• Resisting bedtime
• Struggling to settle independently

While exhausting, these changes are often a sign that your baby is developing new physical and cognitive skills.

Why does sleep regression happen at 8 to 10 months?

Several big milestones often happen around this age.

Physical development

Many babies are learning to:

• Crawl
• Pull themselves up
• Cruise along furniture
• Stand independently

Their brains are so busy practising these new skills that sleep can temporarily take a back seat.

Cognitive development

Your baby's awareness of the world is rapidly expanding.

They begin to understand object permanence and often develop stronger attachment to parents, which can lead to separation anxiety at bedtime.

Nap transitions

Around this age, many babies move from three naps to two, and adjusting to a new routine can temporarily affect overnight sleep.

Teething

Emerging teeth can cause discomfort that leads to more frequent waking or difficulty settling.

Often, it's a combination of all these factors rather than a single cause.

Signs your baby may be experiencing sleep regression

Common symptoms include:

• Frequent night wakings
• Short or inconsistent naps
• Increased fussiness
• Clinginess at bedtime
• Difficulty falling asleep
• Early morning waking
• More reliance on parents for settling

These behaviours can appear suddenly, even after weeks or months of great sleep.

How long does the 8 to 10 month sleep regression last?

For many babies, sleep regression lasts between two and six weeks.

The exact length varies depending on your baby's development, temperament and any other factors such as illness or teething.

The important thing to remember is that this phase doesn't last forever.

How to manage the 8 to 10 month sleep regression

1. Keep bedtime consistent

Babies thrive on predictability.

A calming bedtime routine might include:

• Bath
• Pyjamas
• Story
• Feed
• Cuddle
• Bed

Having familiar cues helps signal that it's time for sleep, even during unsettled periods.

Dressing your baby in a comfortable organic sleepsuit after bath time can become part of that reassuring routine.

2. Protect daytime naps

An overtired baby often sleeps worse at night.

Aim for age-appropriate wake windows and don't be afraid to prioritise naps while your baby works through developmental changes.

Most babies this age still benefit from two daytime naps.

3. Support separation anxiety

If your baby is more clingy than usual, that's completely normal.

Offer reassurance with your voice and presence while still encouraging them to settle in their own sleep space.

Consistency is usually more helpful than introducing lots of new sleep associations.

4. Manage teething discomfort

If teething seems to be affecting sleep:

• Offer appropriate teething toys
• Use chilled (not frozen) teethers
• Follow healthcare advice if pain relief is needed

Addressing discomfort may reduce unnecessary waking.

5. Encourage independent settling

Whenever possible, place your baby into their cot awake but calm.

This helps them practise falling asleep independently, making overnight resettling easier when they naturally wake between sleep cycles.

6. Be patient

Developmental leaps don't happen on a timetable.

Some nights will feel harder than others, but consistency usually pays off over time.

Could clothing affect your baby's sleep?

Comfort plays an important role in quality sleep.

Overheating or restrictive clothing can make settling more difficult.

Choose breathable organic baby clothes that allow your baby to move freely while regulating temperature naturally.

Our organic sleepsuits are made from GOTS-certified organic cotton with soft fabrics and practical two-way zips that make overnight changes easier for everyone.

Create a sleep-friendly wardrobe

A few well-chosen essentials can simplify bedtime:

• Comfortable organic sleepsuits
• Breathable bodysuits for layering
• A soft baby bib for bedtime feeds
• Appropriate tog sleeping bags for the room temperature

Simple routines and comfortable clothing often make evenings feel much calmer.

When should you seek medical advice?

Sleep regressions are common, but it's worth speaking to your GP or health visitor if:

• Sleep difficulties continue for several weeks without improvement
• Your baby seems unusually distressed
• You're concerned about feeding or growth
• You suspect pain, reflux or another medical issue is affecting sleep

Trust your instincts if something doesn't feel right.

A smarter system for growing babies

At Sproot, we know babies outgrow clothes almost as quickly as they outgrow sleep phases.

That's why we're building Sproot Loop - a smarter system for baby clothing that's designed to come back, helping families get more value from every purchase while keeping quality garments in circulation.

Because while sleep regressions eventually pass, great basics should keep working for longer.

Final thoughts

The 8 to 10 month sleep regression can feel relentless when you're in the middle of it, but it's often a sign that your baby is learning, growing and developing exactly as they should.

By sticking to a predictable routine, supporting your baby's changing needs and creating a comfortable sleep environment with soft organic sleepsuits and organic baby clothes, you'll give them the best chance of returning to restful nights.

And remember - this stage won't last forever.
