The helmet should sit level and not rock back and forth or side to side. Also make sure that the straps can be adjusted for a level and snug fit. A child who is involved in the selection process will be more likely to wear the helmet since he or she liked it initially. Never allow your child to ride without wearing a helmet. The majority of serious bicycle accidents involving children occur close to home on quiet neighborhood streets.
Accidents can happen to anyone, anywhere, regardless of their cycling skills.
Praise and reward your child every time he or she wears the helmet. Begin the helmet habit early. Insist that your child wear a helmet beginning with the very first ride. This includes when the child is riding in tandem, either in a child seat or trailer. This way putting on a helmet becomes second nature.
