Κάτι το οποίο συμβαίνει γύρω στους 12 μήνες

Nobody we have met in the injury prevention field recommends taking an infant of less than 12 months in a bicycle child seat, trailer, sidecar or any other carrier. Nobody. And we do not either. New York state law prohibits it. The US Consumer Product Safety Commission thinks it is dangerous to take a child under one year on a bicycle, and here is their rationale:
Maurice Keenan, MD, from the American Academy of Pediatrics [21],
requested that a minimum age of 1 year be reflected on the label for helmets intended for children under age 5. This would better convey the message that infants (children under age 1) should not be passengers on a bicycle under any circumstance.
The Commission agrees with the commenter that children under 1 year of age should not be on bicycles. Children are just learning to sit unsupported at about 9 months of age. Until this age, infants have not developed sufficient bone mass and muscle tone to enable them to sit unsupported with their backs straight. Pediatricians advise against having infants sitting in a slumped or curled position for prolonged periods. This position may even be exacerbated by the added weight of a bicycle helmet on the infant’s head. Because pediatricians recommend against having children under age 1 as passengers on bicycles, the Commission does not want the
certification label to imply that children under age 1 can ride safely.
