Checklist / Car Seat Safety

The Ultimate Car Seat Safety Checklist for Dads

Car seat safety feels like it should be simple — strap baby in, drive. But between LATCH systems, harness height adjustments, rear-facing vs forward-facing debates, and the existential dread of whether it's installed correctly, it gets complicated fast. The good news: once you learn it, you know it. And this is one area where being a detail-oriented dad literally saves lives.

Use this checklist when buying a car seat, installing it for the first time, switching between vehicles, or transitioning to the next stage of seat. Review the installation section at least twice a year.

Choosing the Right Car Seat

Always buy new — never use a secondhand car seat unless you trust the source completelyMust have

You don't know if a used seat has been in a crash, is expired, or has been recalled. If you buy used, only from someone you trust, and verify the manufacture date and recall status.

Check the expiration date — car seats expire (usually 6-10 years)Must have

Plastics degrade over time. Heat, cold, and UV exposure weakens the structure. The expiration date is on a sticker on the seat. Don't use an expired seat, period.

Choose rear-facing for as long as possible — it's 5x saferMust have

Rear-facing is the safest position for the head, neck, and spine. Keep them rear-facing until they max out the seat's height or weight limit. Most convertible seats rear-face to 40-50 lbs.

Make sure the seat fits your vehicle — not all seats fit all carsMust have

Some seats are too wide, too deep, or incompatible with certain back seat configurations. Check the car seat manual AND your vehicle manual for compatibility.

Consider a convertible seat that goes from infant rear-facing to toddler forward-facingRecommended

Convertible seats save money — one seat that lasts from birth to 65 lbs. The trade-off is they don't have a carrier handle, so you can't pop it out and carry it into the restaurant.

Fill out the registration card or do it online. If there's a recall, you'll be notified. Unregistered seats mean you might be using a recalled product and never know.

Installation — Getting It Rock Solid

Use either LATCH or the seat belt to install — not both (unless the manual says to)Must have

LATCH and seat belt are two separate installation methods. Using both can actually make the installation less secure unless the specific car seat manual says it's okay.

The seat should not move more than 1 inch side to side at the belt pathMust have

Grab the seat at the belt path and try to move it. If it moves more than an inch in any direction, it's not tight enough. Tighten until it barely budges.

Check the angle — rear-facing seats need a specific recline angleMust have

Most seats have a built-in level indicator. Too upright and baby's head flops forward, blocking their airway. Too reclined and the seat isn't secure. Follow the indicator.

Route the seat belt or LATCH through the correct path — rear-facing and forward-facing paths are differentMust have

Car seats have clearly marked belt paths for rear-facing and forward-facing. Using the wrong path means the seat isn't secured properly. Read the labels on the seat.

Use a locking clip or lock the seat belt if it doesn't lock on its ownMust have

Pull the seat belt all the way out (which activates the locking mechanism in most cars), then let it retract onto the seat. If your car's belt doesn't lock, use the locking clip that came with the seat.

Attach the top tether for forward-facing seats — alwaysMust have

The top tether reduces head movement by 4-6 inches in a crash. Locate the tether anchor in your vehicle (usually on the back of the rear seat or cargo area). Every forward-facing install needs the top tether.

Get a free installation check at a fire station or inspection stationMust have

NHTSA-certified car seat technicians will check your installation for free. Find one at nhtsa.gov/equipment/car-seats-and-booster-seats. Over 50% of car seats are installed incorrectly. Get it checked.

Buckling Baby In — Every Ride

No bulky coats or snowsuits in the car seatMust have

Puffy coats create space between the harness and the body. In a crash, the body compresses through the coat and the harness is too loose to protect them. Buckle first, then put a blanket or coat over.

Harness straps should be at or below shoulders for rear-facingMust have

Rear-facing: straps at or below shoulders. Forward-facing: straps at or above shoulders. This is the opposite and it matters. Check every time you adjust the harness height.

The chest clip goes at armpit level — not the belly, not the neckMust have

The chest clip keeps the straps on the shoulders. Too low and straps can slip off shoulders. Too high and it's at the throat. Armpit level is the sweet spot.

Do the pinch test — you should not be able to pinch the harness strapMust have

Tighten the harness, then try to pinch the strap at the shoulder. If you can pinch fabric, it's too loose. It should be snug enough that you can't grab any slack.

Check that the harness lies flat — no twists in the strapsMust have

Twisted straps don't distribute crash forces properly and can dig into the body. Straighten any twists before every ride. It takes 5 seconds.

Make sure baby is snug and centered in the seat — no leaningRecommended

If baby is slumping or leaning to one side, use the infant insert if the seat has one. Rolled receiving blankets on either side can provide support for very small babies.

Transitioning Between Seat Stages

Rear-facing as long as possible — don't rush to forward-faceMust have

There is no advantage to turning them forward-facing early. Keep rear-facing until they hit the height or weight limit of the seat. Legs touching the back seat is NOT a reason to turn them.

Forward-facing with a 5-point harness until they max out height or weightMust have

Keep the harness as long as the seat allows. Most forward-facing seats go to 65 lbs. A 5-point harness is safer than a booster's seat belt for as long as it fits.

Booster seat when they outgrow the harness — until the seat belt fits properlyMust have

A booster positions the seat belt correctly on a child's body. They're ready to graduate from a booster when the seat belt crosses the shoulder (not the neck) and the lap belt sits on the hips (not the belly).

Back seat until age 13 — front seat airbags are dangerous for kidsMust have

Airbags deploy with enough force to injure or kill a child. Back seat, middle position is the safest spot. All kids under 13 ride in the back.

When you move to a new seat, get the installation checked againRecommended

Every new seat is a new installation. Every new vehicle is a new installation. Get it checked by a certified tech each time. It's free and it's worth the trip.

Dad Pro Tips

#1Put a small mirror on the headrest facing the rear-facing seat so you can see baby's face from the driver's seat. It reduces the anxiety of not being able to see them and lets you check on them without turning around.
#2Keep a car seat cover in your trunk for restaurant high chairs and shopping carts. The same attention you give to car seat safety should extend to keeping the seat clean — food, dirt, and liquids degrade the harness webbing over time.
#3Set a phone reminder to re-check your installation every 3 months. Seats loosen over time from daily use, getting in and out, temperature changes, and just normal driving. A quick tightness check takes 30 seconds.
