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.
Newborn children up to 2 years of age should be placed in a rear-facing car seat in the back seat. Children from ages 2 to 5 years old should be put in a forward-facing car seat. After the age of 5 or until the seat belt fits the child properly, the child should be in a booster seat. Children should not be taken out of the booster seat until they are 57 inches tall so that the seat belt will fit properly.
