Car seat stage. Rear-facing until the seat's height or weight limit; forward-facing with harness and tether until that limit; booster until the belt fits. CDC/AAP/NHTSA, verified Jul 2026.
Misuse fix. NHTSA reports 46% of observed car seats and boosters had at least one major misuse in the 2011 NCRUSS sample. Use a CPST inspection, not confidence.
Hot car habit. NHTSA reports 31 child vehicular heatstroke deaths in 2025 and record years of 53 in 2018 and 2019. Put the needed item in back, lock parked cars, and use daycare absence calls.
Backover habit. Walk around the vehicle, windows down, children visible at the side before backing. Cameras help; they do not replace a sweep.
Teen GDL at home. If state law is weak, house rule fills the gap: no teen passengers for the initial period, no late-night driving, phone away.
When not to upgrade worry. Do not buy gadgets before fixing fit, harness tightness, back-seat position, and daily use.
