It’s Sick Season as we say in the office
How Illness Affects Your Child’s Sleep (and What to Do About It)
I’ve been seeing a lot of Flu A, strep, and RSV this week — so let’s talk sickness and sleep.
When kids get sick, sleep almost always falls apart. Night wakings increase, naps shorten or disappear, and bedtime suddenly feels impossible. As a Pediatric Nurse Practitioner and Certified Sleep Consultant, I want to reassure you: this is common, expected, and usually temporary — but how you handle sleep during illness can make a big difference in how quickly things recover.
Why Sleep Changes When Your Child Is Sick
When your child is ill, several things are happening at once:
Fever and inflammation disrupt deep sleep
Congestion and coughing make it hard to stay asleep
Pain or discomfort (think sore throat, ear pressure, body aches)
Increased need for comfort and reassurance
Disrupted schedules due to naps, medications, or missed daycare/school
All of this leads to lighter sleep and more frequent night wakings — even for children who normally sleep very well.
What’s Normal (and What’s Not)
Normal during illness:
Extra night wakings
Shorter naps or skipped naps
Earlier bedtimes
Wanting more help falling asleep
Check in with your pediatrician if you notice:
Persistent high fever
Labored breathing or retractions
Signs of dehydration
Severe or worsening pain
(Always trust your instincts — you know your child best.)
Should You Help More With Sleep When They’re Sick?
Yes — within reason.
During illness, it’s appropriate to:
Offer extra comfort
Respond more quickly overnight
Adjust bedtime earlier if needed
Be flexible with routines
This does not mean you’re “ruining sleep” or creating long-term habits. Kids need support when they’re sick, and their nervous systems recover quickly once they feel better.
How to Protect Sleep (As Much As Possible) During Illness
Here are clinically sound ways to support sleep while your child is sick:
Prioritize comfort over schedules — sleep is restorative
Use appropriate pain/fever control as advised by your pediatrician
Elevate the head slightly (for older babies/toddlers, when safe)
Run a cool-mist humidifier for congestion
Stick to the same sleep location if possible
Keep routines familiar, even if shortened
Getting Back on Track After Your Child Is Better
Once symptoms are improving (usually 24–48 hours):
Return to your normal schedule
Resume independent sleep skills
Be consistent but calm
Expect a few nights of adjustment — not a full regression
If sleep doesn’t rebound within 3–5 days, it’s often a schedule or habit issue — not lingering illness.
When to Call or Be Seen by Your Pediatrician
Because I’m seeing a lot of Flu A, RSV, and strep right now, I want to be very clear about when sleep disruption is normal — and when it’s a medical issue.
Call or seek care if your child has:
Persistent or high fever (especially lasting more than 3 days)
Fast or labored breathing, wheezing, or retractions
Signs of dehydration (dry mouth, minimal urine output, no tears)
Severe throat pain, ear pain, or persistent vomiting
Lethargy, poor responsiveness, or a significant change from baseline behavior
If you’re unsure, trust your instincts — disrupted sleep alone is common during illness, but breathing issues, hydration concerns, or worsening symptoms always warrant medical evaluation.
The Big Picture
Illness can temporarily derail sleep, even in great sleepers. The key is support during sickness, consistency during recovery. With the right approach, most families return to solid sleep quickly.
If your child’s sleep hasn’t bounced back — or illness seems to have triggered ongoing issues — I can help.
