If your baby or toddler has been teething or unwell recently, you’ll know how quickly sleep can unravel. Just when you think you’ve cracked bedtime, a cold, fever, or teething pain arrives - and suddenly your little one is waking multiple times a night or refusing to settle.

This is one of the most common frustrations I hear from parents: “My baby won’t sleep after being sick,” or “We were making progress, and then teething ruined everything.”

The good news? You can comfort your child through illness or teething without undoing your sleep progress or creating new habits you’ll later need to break.

Here’s how to manage your child’s sleep during teething, sickness, or recovery - while protecting those precious nights of rest.

Step 1: Identify Why Your Baby Won’t Sleep

Sleep disturbances usually have a clear cause. If your child normally self-settles but is now struggling, consider:

• Teething pain – often worse at night as blood flow increases to the gums.

• Colds and congestion – making it harder to breathe comfortably.

• General illness or fever – leading to restlessness and discomfort.

Recognising the trigger helps you respond appropriately without resorting to sleep crutches.

Step 2: Relieve Discomfort Safely

Always follow safe sleep and health guidelines when easing your child’s symptoms. Practical options include:

• Humidifiers or vapour products to help clear congestion.

• Teething toys or rings to reduce gum pressure (biting relieves pain more effectively than sucking).

• Medical advice or prescribed medication if symptoms are ongoing or severe.

This way, you support your child’s recovery while maintaining healthy sleep boundaries.

Step 3: Offer Extra Comfort and Reassurance

Even the best sleepers need more closeness when they’re unwell. Extra cuddles, sitting nearby, stroking their hair, or offering soothing words provides comfort without creating habits that are hard to break.

It is about balance: being responsive and loving, but also mindful of the long-term impact on your child’s sleep and wellbeing. Do not be tempted to overcompensate - see what they need before you go in offering everything.

Step 4: Avoid Slipping Back Into Old Habits

When your baby won’t sleep during teething or after sickness, it’s easy to fall back on old crutches like rocking, feeding to sleep, or bringing them into your bed. While this feels like the quickest fix, it often makes sleep challenges worse once they’re well again.

Instead:

• Reassure them in their sleep space.

• Stick to familiar bedtime routines.

• Avoid introducing completely new sleep associations (like TV in the middle of the night).

Step 5: Return to Normal Sleep Routines Quickly

As soon as your little one is feeling better, re-establish their usual bedtime routine and independent sleep habits. The longer you wait, the harder it becomes to return to normal.

If sleep was improving before teething or illness, you may need to briefly revisit the strategies that were working. If sleep was already a struggle, this could be the perfect time to invest in lasting solutions.
