After any moderate to severe car accident, it is important to replace your baby car seat, even if there are no visible damages. The impact from an accident can compromise the structural integrity of the seat, potentially reducing its ability to protect your child in future incidents. Contact your car seat manufacturer or insurance company for guidance on replacing the seat, as some may offer replacements in such cases. It's better to be on the side of caution and ensure your child's safety by obtaining a new car seat after an accident.
