Bike seats are used to carry young children safely when you are out cycling. These seats can be fitted behind the rider, on the crossbar or ahead of the handlebars facing the front.
They are adviced to be used for children from 18 months to 4 years.
Bike seats are not suitable for infants under one year old according to the American Academy of Pediatrics. Children are just learning to sit unsupported at about 9 months of age.
Before the age of one infants have not developed sufficient bone mass and muscle tone to enable them to sit unsupported with their backs straight for a prolonged time.
In some states it is even illigal to take a child under one on in a baby bike seat on a bicycle. That's why you probably won't be able to find a baby helmet to fit a child that young.
At the age of one the neck development has come to a point where they can tolerate the weight of a helmet.
