The first few weeks of school are exciting. New teachers, new friends, new backpacks. They are also, without fail, the weeks when every parent’s phone starts blowing up with nurse calls.

It happens every year and it is not bad luck. It is biology. And knowing why it happens, and what to do about it, can make the difference between a rough September and a smoother one.

This guide is for Northern Virginia families getting ready for back-to-school season. Here is what to expect, how to prepare, and when to come in.

Why the First Weeks of School Are Peak Germ Season

Summer is relatively low-exposure for most kids. They are outside more, socializing in smaller groups, and not sharing supplies with 25 other children in an enclosed classroom for seven hours a day.

Then school starts. And everything changes at once.

New classrooms mean new germs

Every child brings a different microbial environment from their summer. When 20 to 30 kids come together in a new classroom, they are essentially sharing immune exposure for the first time. The first few weeks are when that mixing happens most intensely.

Shared supplies and close contact

Shared pencils, shared tablets, shared water fountains, shared everything. Young children also touch their faces constantly, which is the most direct route for respiratory viruses to travel. This is not something you can fully prevent. It is just how school works.

Indoor air and ventilation

Summer means open windows and outdoor time. School means climate-controlled classrooms where the same air circulates. Respiratory viruses spread more easily in these environments, especially in the first weeks before kids have had any exposure to the season’s circulating bugs.

WHAT THIS MEANS FOR YOUR FAMILY Expect your child to get sick in the first few weeks of school. This is normal and not a sign that something is wrong. Most kids get 6 to 8 colds per year. School-age children in their first few years of school can get even more as their immune systems build up.The goal is not to prevent every illness. It is to be prepared when it happens.

How to Help Your Child’s Immune System Going In

There is no supplement or product that will prevent your child from getting sick at school. But there are things that genuinely support immune function heading into the season.

Sleep is the most important one

Immune function drops significantly with inadequate sleep. Back-to-school season often disrupts sleep schedules that drifted over the summer. Getting kids back on a consistent sleep routine two weeks before school starts makes a real difference.

• Toddlers (1 to 3 years): 11 to 14 hours including naps
• Preschool (3 to 5 years): 10 to 13 hours
• School age (6 to 12 years): 9 to 12 hours
• Teens (13 to 18 years): 8 to 10 hours

Make sure vaccines are up to date

This is one of the most concrete things you can do. Virginia school immunization requirements exist precisely because some of the most contagious childhood illnesses spread most easily in school settings. If your child is behind on any vaccines, getting caught up before school starts protects them and everyone around them.

Hydration and real food

Processed snacks and sugary drinks are not going to tank your child’s immune system, but consistent hydration and a diet with fruits, vegetables, and protein genuinely support immune function. The basics matter more than any supplement.

Hand washing, the right way

Boring but true. Teaching kids to wash their hands with soap and water for at least 20 seconds before eating and after bathroom breaks is one of the most effective things you can do. Make it a habit before school starts.

Real Sick-Day Rules: When to Send Them In vs. Keep Them Home

This is the question every parent wrestles with on a Tuesday morning when their child says they do not feel well but seems fine otherwise.

Here is a practical framework.

KEEP THEM HOME

• Fever (confirm threshold with Dr. Dhaliwal) in the last 24 hours
• Vomiting or diarrhea in the last 24 hours
• Pink eye with discharge that has not been treated
• Strep throat until they have been on antibiotics for at least 24 hours
• A rash that has not been evaluated and cleared by a provider
• They seem genuinely unwell and not able to participate in class

OKAY TO SEND

• Mild runny nose with clear mucus and no fever
• Occasional cough with no other symptoms
• A cold they had several days ago that is improving
• Mild allergy symptoms they manage regularly
• Low energy but no fever, vomiting, or diarrhea
• They feel fine but you are worried, trust your gut

When in doubt, call us. We can often help you make the call over the phone or get your child seen same day.

How KidsWatch Covers School-Readiness in One Place

One of the things we hear most from Northern Virginia families is that coordinating school-readiness across multiple appointments is exhausting. Well visit here, vaccines there, vision check somewhere else, school forms from a different office.

At KidsWatch, we try to make that simpler.

Well visits and school forms

We complete well child exams and all required Virginia school health forms at the same appointment, signed same day. If your child needs vaccines, we administer them at the visit. No separate trip required.

Sick visits when it matters

We are open Monday through Friday until 10pm and weekends from 9am to 5pm. When your child gets sick on a Thursday night or a Sunday morning, you do not have to wait until Monday. Same-day sick visits, walk-ins welcome.

Vision screening

We perform vision screenings as part of the well visit. If we see anything that needs a closer look, we refer you to a pediatric optometrist and help coordinate next steps. Vision problems are one of the most commonly missed reasons kids struggle in the first weeks of school.

Care in your family’s preferred language

Northern Virginia is one of the most linguistically diverse communities in the country. We serve families across Falls Church, Fairfax County, and the surrounding area and work to make sure language is never a barrier to getting your child the care they need.
