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.
Even at age 4, most children are NOT ready to use a booster seat. A booster seat just sits on top of the car's seat and the adult seat belt is used to buckle in the child. At this age, most children fidget/ lean out of the belt to tease a sibling or to pick up a toy.
