Frequently Asked Questions
When should I switch from rear-facing to forward-facing?
Keep your child rear-facing as long as possible — ideally until they reach the seat's rear-facing weight or height limit. The AAP recommends rear-facing until at least age 2, but many convertible seats allow rear-facing to 40-50 lbs, which can last until age 3-4.
LATCH or seatbelt installation — which is safer?
Both are equally safe when installed correctly. LATCH is generally easier and has fewer installation errors. However, most LATCH systems have a weight limit of 65 lbs (child plus seat), so heavier toddlers may need seatbelt installation. Always check the seat's manual.
How long does a convertible car seat last?
Most convertible car seats expire 6-10 years from the manufacture date, which is printed on the seat. The plastics and foam degrade over time, reducing crash protection. Never use an expired seat, and never use a seat that's been in a moderate or severe crash.
