The current safety guidelines advise that newborn babies are not left in their car seat for longer than 30 minutes. For babies 2-6 months, no longer than 2 hours. It is also safer to keep your child rear-facing for as long as possible –  a minimum of 15 months but ideally 4 years. A child should never be in their harnessed car seat with a thick winter coat or snowsuit on.
