Atkinson is an English-language surname. The name is derived from a patronymic form of the Middle English Atkin.
These are much more conservative than state laws, in general (for instance, everyone should be in a booster seat from about age 4 to at least age 8) but remain less conservative than some of the european standards (for instance, the European Child Safety Alliance recommends that children remain in rear-facing carseats until 3 years of age).
All children are safer if they remain in a rear-facing car seat beyond a year. Thanks to higher rear-facing weight limits on car seats, nearly all toddlers can remain rear-facing to age 2 and beyond. Some states in the U.S. have begun updating their child passenger safety laws to require rear-facing until age 2.
