Back to School Health: A GP's Guide to Keeping Children Well This Term
By Dr Daniel Gordon • 11, Sept 2026
Every September, I notice the same thing happening in clinic. Bedtimes have drifted, mornings suddenly start earlier again, classrooms fill back up, and within a couple of weeks the familiar round of coughs, colds and stomach bugs starts doing the rounds.
As a GP, this is also the time of year I spend a lot of consultations helping parents work out what's normal, what needs a day at home, and what actually needs a proper look. You can't prevent every infection your child picks up this term. But there are a few simple things worth sorting out before and during the first weeks back that make the whole transition much easier, for your child and for you.
My back-to-school health checklist for parents
A few simple things can make the transition back to school considerably easier. These are the areas I'd encourage parents to think about before the first day and during those first few weeks.
1. Get sleep back on track before the first school morning
Don't leave this until the night before term starts. From my own experience as a parent, gradually moving bedtime and wake-up time over several days works much better than trying to reset everything in one night.
Bring bedtime and wake-up time forward in small steps
Keep the last part of the evening calm and predictable
Reduce stimulating screen time close to bedtime
Choose a routine your family can realistically maintain once term begins
A tired child can be irritable, struggle to concentrate and find mornings much harder. Sometimes what looks like a difficult return to school is simply a child who hasn't yet adjusted to the new routine.
2. Check vaccinations before term gets busy
Back-to-school season is a good natural prompt to check your child's vaccination record, particularly if you're not entirely sure whether any routine doses were missed along the way.
Check routine childhood vaccinations are up to date
Ask about catch-up vaccination if any doses were missed
Look out for the annual flu vaccination offered to school-aged children
If your child has a medical condition or a more complicated vaccination history, it's worth asking for individual advice rather than assuming a generic schedule applies.
Worth flagging: the childhood vaccination programme changed in 2026, including the introduction of MMRV dual MMR and chickenpox vaccination for some younger children. Which vaccine is right depends on age, date of birth and previous doses, so I'd always check the individual record rather than assume every child is following exactly the same schedule.
3. If your child has asthma, check their inhalers before they go back
For many children with asthma, I tend to see symptoms resurface in September that had gone quiet over the summer. Viral infections are a common trigger, and children are also heading back into sport, colder mornings and different indoor environments, all things that can stir symptoms up.
Make sure the school has the right inhaler and up-to-date information. I'd want to see a child for an asthma review if you notice:
More frequent use of the reliever inhaler
Night-time coughing or waking
Breathlessness or wheeze with exercise
A persistent cough that's becoming more noticeable
Common back-to-school health questions I hear from parents
Once term starts, the questions I hear tend to be remarkably similar. Is this cold enough to stay home? How long after a stomach bug? What about head lice? And when does something actually need checking?
Q1. Does every cough or cold mean a day off school?
Usually not. A mild runny nose, sore throat or cough doesn't automatically mean your child needs to stay at home, as long as they're otherwise well and able to take part in a normal school day.
I'd be more cautious if your child has a high temperature, is clearly unwell, seems unusually tired or simply isn't well enough to manage their usual school activities.
Q2. How long should my child stay home after vomiting or diarrhoea?
Stomach bugs can spread very easily in a classroom. The usual advice is to keep children away from school for at least 48 hours after their last episode of vomiting or diarrhoea.
I know this can feel overly cautious, especially when your child seems completely well again within a day. But they can still pass the infection on. Giving them the full 48 hours helps reduce the risk of it spreading to other children and their families.
Q3. Does my child need to stay home with head lice?
Usually, no. Head lice cause a lot of anxiety in school WhatsApp groups, but they're a very common part of childhood and they're not a sign of poor hygiene.
Treat them promptly and check other close family members. A child who is otherwise well doesn't usually need to miss school simply because head lice have been found.
Q4. Could those tummy aches actually be anxiety about school?
Sometimes, yes. A child who's anxious about returning to school may complain of headaches, nausea, tummy aches, poor appetite or trouble sleeping. I want to be clear about something here: these symptoms are real, even when anxiety is what's driving them.
Rather than repeatedly asking "do you feel ill?", it's often more useful to gently explore what might be sitting behind it:
A new teacher or classroom
Friendship problems or bullying
Worries about schoolwork
Separation anxiety
Sensory overload or difficulty with the school environment
If this pattern keeps repeating, or attendance starts becoming a genuine struggle, speak to the school early and consider bringing your child in to see their GP. Long periods of avoidance tend to make going back even harder, so earlier is better than later.
Q5. When should I get my child checked?
Most of the coughs, colds and minor illnesses I see in children settle on their own with rest, fluids and time. What matters is how your child is doing overall and whether they are improving as you would expect.
I would recommend getting medical advice if your child is getting worse rather than better, or if you notice something that feels significantly different from how they usually are when they're unwell. Things I would pay particular attention to include:
Difficulty breathing or breathing much faster than usual
Being unusually sleepy, difficult to wake or less responsive
Not drinking enough or showing signs of dehydration
A high temperature that persists or is accompanied by other concerning symptoms
A rash that you're worried about
Severe or worsening pain
A child who simply doesn't seem themselves and is causing you concern
Parents know their children better than anyone. If you're worried about a change in their behaviour or symptoms, particularly if they're getting worse, it's reasonable to have them checked.
If your child is seriously unwell, struggling to breathe, difficult to wake or unresponsive, seek urgent medical help.
The key takeaway
Back-to-school health is mostly about getting the basics right. Get sleep back into a routine, check vaccinations and regular medications are up to date, keep children at home when they're genuinely unwell, and pay attention when symptoms aren't improving or keep coming back.
Coughs, colds and minor illnesses are an inevitable part of school life. As a GP, what I want parents to feel more confident about is knowing the difference between an illness that simply needs rest and time, and the signs that tell us a child may need to be checked.
