Carseats and boosters should NEVER be installed in side-facing jump seats. Unfortunately, that means that children under 8 years old (about 80 pounds) should not ride in these types of seats. Children should never ride in the cargo area of a pickup. Rear-facing seats in wagons vary.
Group 1/2/3 child car seats. There are many Group 1/2/3 seats available, which can be used from nine months all the way up to 12 years (9-36kg). These allow you to secure your baby in a five-point safety harness, then it converts to a high-backed booster seat when your child is older and bigger. Generally, car seats designed to span more than two groups do not always provide good levels of protection in all weight groups, but there are some exceptions.
