Atkinson is an English-language surname. The name is derived from a patronymic form of the Middle English Atkin.
Once children outgrow their booster seat (usually at 10 â 12 years old) they can use the adult lap/shoulder safety belt if it fits them properly. Lap portion low over the hips/tops of thighs and shoulder belt crosses the center of the shoulder and center of the chest.
As a guide children under the age of 12 should sit in the back seat on the correct child seat for their age, so for your son of 7 that would be a booster seat. Contrary to popular belief the safest place for a child to sit is the middle seat of the back seat of the car, as long as it has a 3 point seat belt.
