If your baby's sleep has suddenly changed, you've probably wondered...

"Is it teething?"

It's one of the most common questions we hear from parents, and understandably so. When your little one starts waking more overnight, refusing naps or becoming unsettled, teething is often the first thing that comes to mind.

But does teething really cause sleep problems?

The short answer is yes... but usually only temporarily.

Does Teething Affect Sleep?

As a new tooth moves through the gums, your baby may experience some discomfort that can make them a little more unsettled than usual.

You might notice:

• More dribbling
• Wanting to chew on everything
• Swollen or tender gums
• Extra clinginess
• Mild irritability
• A few disrupted naps or overnight wakes

For babies who already know how to self-settle, these sleep disruptions are often short-lived. They may stir a little more between sleep cycles but are usually able to settle themselves back to sleep.

If your baby has been waking every hour for weeks, however, it's unlikely that teething is the only cause.

How Long Does Teething Last?

Research suggests that teething symptoms tend to occur within a fairly small window around the tooth erupting.

Typically you may notice symptoms:

• Around four days before the tooth appears
• On the day the tooth erupts
• Up to three days afterwards

While every baby is different, prolonged sleep disruption lasting several weeks is unlikely to be explained by teething alone.

Is It Really Teething... or Something Else?

If sleep has become difficult for longer than a few days, it's worth looking at the bigger picture.

Ask yourself:

Is your baby happy during the day?

Teething discomfort doesn't usually appear only at bedtime. If sore gums are the cause, your baby will often seem unsettled throughout the day as well.

Is your baby around 4 months old?

Around this age, babies experience a major change in their sleep cycles (commonly known as the 4-month sleep regression). This often causes more frequent night waking and shorter naps.

Is your baby between 6 and 8 months?

This is a busy stage of development.

Your baby may be:

• Learning to roll or crawl
• Adjusting to solid foods
• Experiencing changing sleep needs
• Ready to transition from three naps to two

All of these developmental changes can temporarily affect sleep.

Has your baby's routine changed?

Sometimes overtiredness, undertiredness or needing an adjustment to awake windows can have a much bigger impact on sleep than teething itself.

Common Teething Symptoms

Signs that may be related to teething include:

• Rosy cheeks
• Increased drooling
• A mild rash around the mouth from excess saliva
• Swollen gums
• Wanting to bite or chew
• Mild irritability

Remember, not every baby experiences every symptom.

Symptoms That Are Not Usually Caused by Teething

Despite common myths, teething does not typically cause:

• High fever
• Diarrhoea
• Persistent nappy rash
• Ongoing illness

If your baby develops a true fever, persistent diarrhoea, seems unusually unwell, or you're concerned for any reason, it's important to seek medical advice from your GP or healthcare provider.

What Can You Do to Help?

If your baby is teething, offer plenty of comfort during the day and use safe teething relief if recommended by your healthcare professional.

At bedtime, try to keep your sleep routine as consistent as possible.

If your baby can usually fall asleep independently, they'll often be able to resettle themselves once the brief discomfort has passed.

Teething can absolutely make sleep a little bumpier for a few days.

But if your baby has been waking frequently for weeks, taking short naps or suddenly needing much more help to fall asleep, it's worth looking beyond teething.

More often than not, sleep disruptions are linked to developmental changes, changing sleep needs or sleep associations - not just those tiny new teeth.
