The first sign is rarely vomit. It is the quiet.
Your kid stops arguing about the aux cord. They go pale. They swallow a lot. They stare at the seat back. By the time they say they feel sick, you are already looking for a shoulder.
P6 is a Wyoming family that made kid-size bands because their own kids got carsick on long rural drives. Here is what to do in the car, where the band goes, and when a patch is the better grab.
These products may help with motion-related nausea. They are not medicine. They do not treat disease. If vomiting is severe, persistent, or your child has other symptoms — fever, a stiff neck, a blow to the head, they cannot keep fluids down — talk to a doctor. Do not wait that out on the highway.

When it shows up
The inner ear feels motion. The eyes see a seat back or a tablet. The brain does not like the disagreement. It hits hardest in the back — especially the third row — on a winding or hot road, on an empty or greasy stomach, with a screen in their lap.
Some kids get it on the school run. Some only on the four-hour drive to the grandparents. Short trips are why a lot of parents do not want a drowsy medicine every time they leave the driveway.
Watch for yawning, sudden quiet, a flush then pale, swallowing, "I want to stop." That is the window. After they are green, you are in damage control.
What to do in the car
Do the boring things first. They work more often than a new gadget.

Front seat if it is safe and legal. If your child's age, height, and your state's rules allow it — and the airbag situation is okay — the front passenger seat is kinder than the way-back. They can see the road. Check your car manual and local car-seat law before you move anyone.
Cool air on the face. Crack their window or point a vent at them. Heat makes this worse. A stuffed car does not help.
Horizon, not the side glass. Have them look out the windshield at a far point, not at trees whipping past the side window. Looking down at a book or a phone is the fastest way to lose the morning.

Screens if they trigger them — off. Some kids can watch a show and stay fine. A lot cannot. If screens have ever been part of a sick day, put the tablet away before the highway. Audiobooks. Music. An "I spy" that does not require looking down.
Snacks, not a feast. A dry cracker or a little something in the stomach is better than empty or greasy. Skip the gas-station burrito. Small sips of water. Not a giant slushie.
Breaks before they throw up. If they say they feel off, do not "see if it passes" for 40 more miles. Pull off. Walk. Sit facing the horizon. A five-minute stop is cheaper than cleaning the booster.
Keep a zip bag, wipes, and a spare shirt where you can reach them.
Put the band on before you pull out

P6 Motion Sickness Bands for Kids are child-size acupressure bands. Cotton band, plastic stud, two in the pack, travel case in the box. Drug-free. Not a medicine. Not scopolamine.
Put them on before the drive. The brand FAQ says nausea is typically reduced within about five minutes once they are on. You still get a better shot if the stud is already on the right spot when you leave the driveway — not after they have gone quiet in the third row.
Where it goes. The P6 / Nei-Kuan point is on the inner wrist, about three finger-widths up from the wrist crease, between the two tendons. Use their fingers, not yours. The plastic stud presses on that point. One band on each wrist. Both wrists.
Snug, not a tourniquet. It has to fit snugly or the stud will wander. If it hurts, or the hand looks puffy, loosen it or take it off. Prolonged use may cause swelling. Remove the bands if there is swelling or pain.
The FAQ says families have used them successfully on kids as young as 3 — if the band actually fits. A floppy band on a tiny wrist is jewelry. If it still slides, this is not the product for that kid yet.
Keep a pair in the glove box, in the case they come with.

If they are already sick
Pull over if you can. Cool air. Horizon. A sip of water when they are ready. You can still put the bands on. Get the point right. Give it a few minutes. These bands are not a drug. Do not stack them with adult motion-sickness medicine unless a doctor told you to.
When a patch is the better grab
Bands fail for kid reasons that have nothing to do with acupressure. They hate things on their wrists. They take the band off. They sweat and it creeps.

P6 Motion Sickness Patches for Kids are a different product. Ages 6+. All-natural ginger and cinnamon. Non-drowsy. Disposable — not reusable. About $24.99 on Amazon as of this writing, with a small review count so far.
They are not prescription scopolamine patches — the drug patches that also go behind the ear. Same place on the box photo. Completely different product. P6 patches are ginger and cinnamon. Do not use an adult scopolamine patch on a child unless a clinician told you to.
The box shows the patch behind the ear and says effective for up to 12 hours. Follow that. If the insert in your box says something different, the insert wins. If your child is under 6, skip the patches.
A patch can be the better grab on a long drive for a 6+ kid who will pick a wristband off. A band is the better grab for a 3- or 4-year-old who will leave it on, and for any trip you want to reuse the same pair. Some families keep both in the console and pick that morning.
What this is not
This is not a treatment for a stomach bug, a concussion, or anything that is not motion. If a product does not help, try the seat, the air, the horizon, and a break. Talk to their doctor if the vomiting is out of proportion to the drive, keeps going after you stop, or comes with other symptoms.
Next trip, put the bands on before you start the car.
