All infants should remain rear-facing until at least one year of age and at least 20 pounds. The following images are types of infant seats and their correct and incorrect usage:


Infant Only Seat

(rear-facing with base)

Correct Usage Infant Only Seat


  • Rear-facing

  • Carrying handle is down in its back locked position

  • Good head and neck support

  • Seat belt correctly routed through base

  • Correct positioning of retainer clip on infant's chest at armpit level
