Research rear-facing infant seatsEssentialDo

Rear-facing until at least age 2 or until they outgrow the height/weight limit. Convertible seats last longer but infant carriers are easier to carry.

Check vehicle compatibilityEssentialDo

Not every seat fits every car. Check the seat manufacturer's fit guide and measure your back seat before buying.

Register the car seat with the manufacturerEssentialDo

Takes 2 minutes online. If there's ever a recall, they'll contact you directly instead of you finding out by accident.

Check the manufacture and expiration dateEssentialDo

Car seats expire 6-10 years from manufacture date. Never use a secondhand seat if you don't know its full history.

Choose LATCH or seatbelt installation methodEssentialDo

LATCH is easier but has a weight limit (usually 65 lbs combined child + seat). Seatbelt works for any weight. Never use both at the same time.

Install the base at the correct angleEssentialDo

Most bases have a built-in level indicator. Newborns need a more reclined angle (30-45 degrees) to keep their airway open.

Perform the 1-inch movement testEssentialDo

Grab the base where the seatbelt or LATCH connects and pull hard. It should not move more than 1 inch side to side or front to back.

Check the recline angle indicatorEssentialDo

The level bubble or line should be in the green zone. If not, use a rolled towel under the base to adjust. Recheck after adjusting.

Route the harness straps correctlyEssentialDo

For rear-facing, harness straps go through slots at or below baby's shoulders. Chest clip sits at armpit level.

Do the pinch test on harness strapsEssentialDo

Tighten straps, then try to pinch the strap at baby's shoulder. If you can pinch a fold of webbing, it's too loose.

Schedule a fire station or police inspectionEssentialDo

Free car seat checks are available at most fire stations and some police departments. Call ahead - not all locations have certified technicians on duty.

Read the car seat manual cover to coverEssentialDo

Every seat is different. YouTube videos are great but your specific manual is the final authority on installation for your model.

Read your vehicle owner's manual car seat sectionEssentialDo

Your car may have specific LATCH anchor locations or seatbelt lock-off features you don't know about. Check pages on child restraints.

Practice buckling in a baby-sized doll or stuffed animalDo

Use a 7-8 lb stuffed animal to practice strapping in. Get the harness adjustment and chest clip placement muscle memory down.

Practice removing and reinstalling the carrier from the baseEssentialDo

You'll do this dozens of times. The click-in and release mechanism should be second nature before baby arrives.

Time yourself on a full install and removalDo

You should be able to install the base from scratch in under 10 minutes. If you can't, practice more or get it inspected.

Install a back seat mirrorEssentialDo

Clips to the rear headrest so you can see baby's face in your rearview mirror. Essential for rear-facing peace of mind.

Add window shades on rear windowsDo

Static cling shades block sun without suction cups falling off. Keeps baby cool and prevents sunburn on the drive home.

Stock a car emergency kitEssentialDo

Extra diapers, wipes, change of clothes, blanket, plastic bags in a small bin in the trunk. You will need this sooner than you think.

Remove any loose objects from the rear shelf and back seatEssentialDo

In a sudden stop, a water bottle becomes a projectile. Clear the back seat area completely around the car seat.
