Group 0+: for babies up to 13kg (29lbs) roughly from birth to 12-15 months.
Group 0+ Carseats are rear facing carrying car seats.
Rearward-facing seats provide greater protection for the baby's head, neck and spine. So, it is best to keep your baby in a rearward-facing seat for as long as possible. Only move them to a forward-facing seat once they have exceeded the maximum weight for the baby seat, or the top of their head is higher than the top of the seat.
