Every camp drop-off, Target errand, or walk to the playground feels heavier in this heat. With sweltering temperatures blanketing much of the U.S., parents are making split-second judgment calls all day long. Is it safe to walk? Should we skip swim class? Can my toddler nap in their stroller? Decision fatigue is real.
As of June 23, 2025, tens of millions of people across the eastern U.S.—from Minnesota to Maine and throughout the South—are under heat advisories, with the National Weather Service warning of dangerous, even “life-threatening” conditions through midweek. Cities like Philadelphia have declared heat emergencies, and forecasts show heat indexes hitting up to 108°F in places like Columbus, Pittsburgh, and Boston.
When you’re parenting in a heatwave, nothing feels simple. Here’s how to stay one step ahead—and keep you and your little ones cool, hydrated, and safe.
Hot car safety: It happens faster than you think
Even on an 80-degree day, the temperature inside a parked vehicle can reach 99 degrees in just 10 minutes—and up to 109 degrees within 20, according to the National Weather Service. During a heatwave, that climb happens even faster. And because babies and young children heat up three to five times faster than adults, a quick errand can turn tragic.
From 1998 through 2024, more than 1,000 children in the U.S. have died from heatstroke after being left in vehicles.
As of June 2025, seven more children have already died in hot cars this year, according to KidsAndCars.org—a heartbreaking reminder of how urgent this issue remains.
Most parents believe they could never forget their child in a car. But research shows this assumption can be dangerous.
David Diamond, Ph.D., a cognitive neuroscientist who has extensively studied these tragedies, emphasizes that these incidents are often rooted in how human memory works—not in a parent’s character or intent. His research shows that stress, exhaustion, and changes in routine can interfere with prospective memory, which is responsible for helping us remember to carry out future tasks. When that system breaks down, even attentive, loving parents can lose awareness of a child in the backseat.
When those systems fail, even the most devoted caregivers can mistakenly believe they’ve already dropped their child off, or forget they’re there at all.
Summer, with its shifting routines and extra mental load, creates a perfect storm.

What puts kids most at risk?
According to data from NoHeatStroke.org:
- 53% of pediatric hot car deaths involve a caregiver forgetting the child was there.
- 24% involve children gaining access to an unlocked vehicle and becoming trapped.
- Less than 22% involve a child who was knowingly left in the car.
In many of these heartbreaking cases, the child was never supposed to be in the car—or wasn’t typically dropped off by that caregiver.
How to protect your family during this heatwave
When the heat climbs into the triple digits, keeping kids safe takes more than sunscreen and frozen snacks. For families without reliable access to air conditioning—or those in dense urban neighborhoods where heat lingers longer—these risks can be even greater. Making a plan, even if it’s just adjusting your routine or choosing shaded spaces, can help.
On your way to camp drop-off…
Scan the backseat before you walk away.
This isn’t just about checking a box—it’s a buffer against decision fatigue. When your brain is full of drop-off logistics, calendar reminders, and mental to-dos, this one 2-second habit can override a moment of forgetfulness.
Before running that 2-minute Target errand…
Place your phone or wallet in the backseat.
Yes, even if you’re “just popping in.” If your essentials are with your child, you’ll always go back—and that’s the point.
When the drop-off routine changes…
Ask your childcare provider to text if your child doesn’t arrive.
Sometimes the mental script gets disrupted—like when your partner does drop-off instead of you. A simple system with daycare can add a safety net you’ll both be grateful for.
Before you close the garage…
Build a habit of locking your car—even in your own driveway.
Kids are naturally curious, and an unlocked car can feel like a playground. This 5-second habit helps prevent a hidden danger most families never see coming.
When you toss your keys on the counter…
Make your keys less accessible to small hands.
Key fobs are powerful—and easy to trigger. A high shelf or locked drawer turns off the temptation for little explorers.
And before you even step outside…
Hydrate your kids, not just their water bottles.
Don’t wait until your child says they’re thirsty. Offer water often—especially before heading to splash pads, playgrounds, or sports practice. Kids need more than they think they do.
Planning a playground stop?
Touch the equipment first.
Slides, swings, and buckles can burn tender skin in seconds. If it feels hot to your hand, it’s too hot for your child. Consider parks with shade or plan visits earlier in the day.

How to talk to caregivers about heat safety
Don’t assume everyone knows the risks. If your child is spending time with grandparents, sitters, or camp staff, be clear about your expectations.
- Be direct and kind. Try: “I know it’s hot out this week, so I wanted to review a few things we’re doing to keep [child’s name] safe.”
- Mention car safety specifically. Ask them to always check the backseat and never leave the car unlocked, even at home.
- Provide backup water and extra clothes. Let them know it’s okay to take breaks, go inside, or skip the playground if it’s too hot.
- Post or text a cheat sheet with signs of heat exhaustion, emergency contacts, and reminders like “never leave the car unlocked” and “offer water every 30 minutes.”
A quick conversation today could prevent tragedy tomorrow. And it shows your caregivers that safety is a shared responsibility—not a solo task moms should carry alone.

Signs of heat-related illness in kids
Even with precautions, young children’s bodies are more vulnerable to overheating—heat-related illness can develop quickly and escalate without obvious warning signs.
Here are some signs to watch for, based on guidance from the Mayo Clinic and the American Academy of Pediatrics (AAP):
- Flushed cheeks or unusually warm skin
- Unusual fatigue or difficulty waking
- Irritability or fussiness without a clear reason
- Fewer wet diapers than usual or dark yellow urine
- Dizziness or confusion in older children
- Rapid breathing or heartbeat
- Dry mouth or no tears when crying
- Vomiting or signs of dehydration
What to do next
If you notice one or more of these symptoms:
- Move your child into a cool, shaded place—ideally indoors with air conditioning, as recommended by the CDC.
- Offer water or breast milk/formula if they’re alert and able to drink.
- Loosen or remove excess clothing and gently sponge their skin with lukewarm water to help bring their body temperature down.
- Stay close and monitor your child carefully.
If symptoms don’t improve quickly—or if your child becomes confused, sluggish, or stops responding—call your pediatrician or 911. As the AAP emphasizes, heat exhaustion can escalate to heatstroke if untreated, so early action is essential.
You don’t need to panic—but you do need to act. Trust your instincts. It’s always okay to call your child’s doctor for guidance—you know your child best.
And a quick note for moms
You matter, too. If you’re sweating through every chore, skipping meals, or feeling completely touched out by noon, that’s your body asking for a pause.
Drink the water. Take the break. Lower your standards for a few days. Your kids need you safe and standing—not pushing through heat exhaustion because you felt guilty resting.
A final reminder: memory can fail—even when love doesn’t
No parent wants to imagine the unthinkable. But taking a moment to recognize the risk is one of the most protective things we can do. As Dr. Diamond puts it, “We have to accept that the human memory is flawed. That includes when loving, attentive parents lose awareness of their children when they are in a car.”
Let this heatwave serve as a cue: stop, look, and lock—every single time.
You’re not careless. You’re carrying a lot. Let this be your reminder to pause, breathe, and double-check—because protection starts with presence.
