Every parent knows the feeling.

Your child wakes up and says they do not feel well. School starts in an hour. You have a meeting at 9am. Your brain immediately starts running through the possibilities. Is this real? Is it nerves? Are they actually sick or are they just not ready to face a Monday morning?

This is one of the most common dilemmas in parenting. And it comes up over and over again once the school year starts.

We built this guide to take the guesswork out of it. Because the answer matters, not just for your child, but for their classmates, their teachers, and your peace of mind.

Keep Them Home If

These are the situations where keeping your child home is the right call, no second-guessing needed.

Fever of 100.4°F or higher.

Most schools in Northern Virginia require children to be fever free for at least 24 hours before returning to school, without the use of fever-reducing medication like ibuprofen or acetaminophen. A child with a fever is still fighting an active infection and is likely contagious. Keep them home, let them rest, and make sure the fever has been gone for a full 24 hours on its own before sending them back.

Vomiting or diarrhea in the last 24 hours.

Even if your child seems completely fine by morning, vomiting or diarrhea within the last 24 hours means they are still in the contagious window for most gastrointestinal illnesses. The 24-hour rule applies here too. Fever free and symptom free for a full day before returning.

A rash that has not been evaluated.

Rashes can signal everything from a viral illness to an allergic reaction to something contagious like hand foot and mouth disease or impetigo. A rash that has not been evaluated and identified by a provider should not go to school. Come in to Night Watch and we can tell you exactly what you are dealing with and whether your child can return.

Pink eye with discharge that has not been treated.

Bacterial pink eye is highly contagious and spreads rapidly in classroom settings. If your child has significant eye discharge that has not been evaluated or treated, keep them home. Once bacterial pink eye has been diagnosed and treated with antibiotic drops, most schools allow return after 24 hours of treatment. Viral and allergic pink eye behave differently and may not require treatment. Come in so we can tell you which type your child has.

They are too unwell to participate in normal school activities.

This one requires parental judgment. If your child is exhausted, in significant pain, or clearly not well enough to sit through a school day, keep them home. A child who is struggling to function is not going to learn anything meaningful and they may need rest more than anything else.

They Can Usually Go to School If

These situations generally do not require keeping a child home, though every child and every situation is different.

Mild runny nose with no fever and they feel okay.

A clear runny nose without fever is often just seasonal allergies or the tail end of a cold. If your child feels okay, is eating normally, and has the energy to get through a school day, they are generally fine to go. Remind them to wash their hands frequently and use tissues rather than wiping on their sleeve.

A cough that is not getting worse and no other symptoms.

A mild cough on its own, particularly without fever, significant fatigue, or other symptoms, is usually not a reason to stay home. Monitor it and make sure it is not worsening over the following days.

A stomach ache that only appears on school mornings and disappears by mid-morning.

This is one of the most common things we see in our clinics in the first weeks of school. A child who has a stomach ache every single school morning but is completely fine on weekends and holidays is almost always experiencing back to school anxiety rather than a physical illness. The gut-brain connection is real and very common in children. The stomach ache is not made up. But the right response is usually a conversation rather than a sick day.

If this pattern keeps repeating, come in for a well child visit. We can rule out anything physical and help you figure out the next step.

They had a fever yesterday but have been fever free for a full 24 hours.

If your child had a fever that resolved on its own, without fever-reducing medication, and they have been completely fever free for a full 24 hours, they are generally ready to return to school. Make sure they are eating, drinking, and have the energy for a school day before sending them back.

Come In to Night Watch If

These are the situations where your child needs to be evaluated before you make the call on school.

A fever that has lasted more than three days without improving. A sore throat with fever and no runny nose or cough, which may be strep throat and requires a test to confirm. A rash you cannot identify. Ear pain that started after a cold. Pink eye with thick or yellow discharge. Symptoms that are getting progressively worse instead of improving after the first few days. A cough that has lasted more than two weeks. Or simply something that just does not feel right to you as a parent.

You know your child better than anyone. If your gut is telling you something is off, trust it and come in. We would rather check and reassure you than have you managing something serious at home.

Go Straight to the ER or Call 911 If

These situations require emergency care and should not wait for urgent care.

Difficulty breathing or labored breathing. A severe allergic reaction with throat swelling, hives, or difficulty swallowing. Loss of consciousness or a seizure. A fever in an infant under 3 months old, which always requires emergency evaluation. A severe headache accompanied by a stiff neck, which can indicate meningitis. Any situation that feels like a true emergency.

When in doubt between urgent care and the ER, call 911 or go to the nearest emergency room. Night Watch will always tell you honestly if your child needs a higher level of care.

A Note on the School Morning Sick Day Debate

One of the hardest parts of this guide to write is the section on stomach aches and school avoidance. Because the reality is that both things can be true at the same time.

A child can have genuine back to school anxiety that produces real physical symptoms, and also be coming down with something. A child can be faking illness some days and genuinely sick on others.

The pattern is usually the most helpful clue. A child whose symptoms consistently appear on school mornings and resolve by mid-morning, who is completely well on weekends and holidays, and who has no fever or other physical symptoms, is almost certainly experiencing anxiety rather than illness. That anxiety is real and deserves attention, but a sick day is often not the right response.

A child whose symptoms do not follow a predictable pattern, who has a fever or other physical signs, or who seems genuinely unwell regardless of the day, needs to be evaluated.

When you are not sure which one you are dealing with, come in. We see both every single week and we can help you figure out what your child actually needs.
