Does your child crash after the first week of school?
You're not imagining it.

Does your child fall apart after the first week of school?
You’re not alone and it’s not just a “phase.”

Many children experience what I call back-to-school burnout. Between early mornings, social transitions, new classroom expectations, and constant exposure to germs, their nervous systems go into overdrive. Mood swings, belly aches, and poor sleep are often the first signs.

What most parents don’t realize is that much of this is connected to one powerful nerve and you’ve probably never heard it mentioned in a school readiness checklist.

The Vagus Nerve: Your Child’s Internal Regulator

The vagus nerve runs from the brain through the face and down to the gut. It plays a critical role in regulating digestion, heart rate, immune function, mood, and sleep. Think of it as the body’s natural reset button.

When the vagus nerve is overworked or under-stimulated, kids may show signs of:

• Difficulty focusing
• Increased irritability
• Gastrointestinal symptoms (like nausea, constipation, or stomach pain)
• Sleep disturbances
• Heightened anxiety or sensory overwhelm

When the vagus nerve is functioning well, kids tend to adapt more easily to stress, fall asleep faster, and handle change with greater emotional resilience.

Here are five research-supported ways to strengthen your child’s vagus nerve and support their body and mind as they return to school.

1. Rebuild a Healthy Sleep-Wake Cycle

Why this matters: Sleep is essential for immune health, memory, attention, and emotional regulation. It also plays a key role in vagus nerve function and helps the body respond to daily stressors.

What to do: Start shifting bedtime 15–20 minutes earlier every few nights until your child is back on a school-friendly sleep schedule. This gradual adjustment helps avoid power struggles and improves long-term consistency.

Parent tip: Use a consistent bedtime routine that includes calming cues like dim lights, gentle music, lavender lotion, or reading a favorite book. Predictability helps the brain wind down more quickly.

Research-backed insight: Studies have shown that structured bedtime routines improve sleep quality in children and help with emotional stability.

2. Support Gut Health to Improve Mood and Immunity

Why this matters: Over 70 percent of the immune system resides in the gut, which is directly connected to the brain via the vagus nerve. A healthy gut can improve focus, reduce anxiety, and help prevent frequent school-related illnesses.

What to do: Serve a fruit or vegetable with every meal, and vary the colors to provide a wide range of vitamins, minerals, and gut-friendly fiber.

Parent tip: Turn it into a game ask your child how many colors they can eat in a single day. This keeps things fun and encourages variety without pressure.

Research-backed insight: Diets rich in plant-based fibers have been shown to enhance communication between the gut and brain and help regulate mood and behavior.

3. Use Simple Techniques to Stimulate the Vagus Nerve

Why this matters: When the vagus nerve is stimulated in small, regular ways, the body becomes better at calming itself. This improves focus, emotional regulation, and even sleep quality.

What to do: Incorporate daily activities that activate the vagus nerve. These include:

• Slow belly breathing (inhale for 4 seconds, exhale for 6 seconds)
• Humming, singing, or chanting
• Splashing cold water on the face
• Gargling while brushing teeth

Parent tip: You can make these activities part of your child’s morning or bedtime routine. Singing together or blowing bubbles are easy ways to sneak in this practice during playtime.

Research-backed insight: Stimulating the vagus nerve has been associated with improvements in anxiety, emotional resilience, and sleep.

4. Limit Processed Snacks to Protect the Gut and Mood

Why this matters: Many summertime foods like popsicles, chips, and sugary cereals can disrupt blood sugar, irritate the gut lining, and contribute to emotional instability and poor sleep.

What to do: Gradually transition to less processed snacks. Try whole food options such as:

• Sliced apples with nut butter
• Greek yogurt with berries
• Air-popped popcorn with a sprinkle of cinnamon

Parent tip: Offer two healthy snack choices to give your child a sense of control. This strategy reduces food resistance and builds independence around nutrition.

Research-backed insight: Highly processed foods are linked to increased inflammation, poorer mental health, and disrupted circadian rhythms.

5. Schedule a Back-to-School Physical Before the Rush

Why this matters: Most schools require physicals for enrollment, sports participation, or medication clearance. But more importantly, this annual checkup helps identify red flags you may not notice—like sleep problems, chronic tummy troubles, or school-related anxiety.

What to do: Don’t wait until the last minute. Booking early ensures you get forms completed and concerns addressed before the school year begins.

Parent tip: Bring all required forms to your appointment, including any medication or asthma plans. A single, well-prepared visit can take care of everything at once.

Research-backed insight: The American Academy of Pediatrics recommends yearly well-child visits to monitor development, manage chronic conditions, and support emotional well-being.
