If left to their own devices, child cyclists may just go helmetless. So don't leave them to their own devices. Instead, make sure that the Louis Garneau Brat Helmet is on hand to keep kids covered while they're covering miles. It's modeled as the wee version of LG's Raid adult helmet, so its shell extends--especially in back--to increase the area covered by the impact-absorbing EPS foam body and polycarbonate shell.
