You can typically use the Nuna PIPA infant car seat for about 12 to 18 months, depending on your baby's growth. The exact duration is determined by two key factors: the seat's expiration date (usually 6-7 years from manufacture) and your child reaching either the height or weight limit. The PIPA is a rear-facing-only seat designed for infants, with most models having a weight limit of 32 pounds and a height limit of 32 inches. Always prioritize these limits over age.
The most critical factor for safety is the expiration date. Like all car seats, the Nuna PIPA has one due to material degradation over time. You can find this date on a sticker on the seat itself or imprinted on the shell. Using a seat past this date is not safe.
Your child will outgrow the seat when the top of their head is within one inch of the top of the seat shell or when they reach the maximum weight limit, whichever comes first. Many children reach the height limit before the weight limit. After outgrowing the PIPA, you'll need to transition to a convertible car seat.
