Most newer safety guidelines do not give a single “magic” weight for turning a baby forward-facing; instead they say to keep your child rear-facing as long as possible, until they hit the height or weight limit for rear-facing on their specific car seat (whichever comes first).

The Key Rule (Not Just Weight)

  • Check your car seat manual: it lists a rear-facing max weight and height; many modern convertible seats allow rear-facing up to about 30–50 lb, but your exact numbers may differ.
  • You only switch once your child exceeds either the rear-facing weight limit or the rear-facing height limit for that seat, not when they reach some general age or “big kid” look.
  • Age is the least important factor; experts recommend rear-facing as long as the seat allows, because it better protects the head, neck, and spine in a crash.

Historically, you may see older advice like “20 lb and 1 year,” or forward- facing allowed from around 22 lb on some labels, but current pediatric and safety guidance stresses that “allowed” is not the same as “safest.”

Practical Example

Imagine a convertible car seat that rear-faces up to 40 lb or 40 inches tall.

  • If your toddler is 32 lb and 37 inches, they should still ride rear-facing in that seat.
  • You would turn them forward-facing only after they exceed either 40 lb or 40 inches, as written in the manual.

What You Should Do

  1. Read the labels on your child’s car seat and the instruction manual for rear-facing limits (both weight and height).
  1. Keep your child rear-facing until they outgrow those limits, even if they meet some generic “20–22 lb” suggestion you see online or on older seats.
  1. If you’re unsure, a certified car seat technician or your pediatrician can look at your child’s stats and your exact seat to give tailored guidance.

Bottom line: There is no one universal “correct” weight like 20 or 22 lb; you follow your specific seat’s rear-facing limits and only turn forward when your child has outgrown them, keeping them rear-facing as long as possible for maximum safety.
