does anyone know if there is anything on the market that secures the seatbelt to thus stop it slipping down my daughters arm away from her shoulder as she has developed a habit of falling asleep and slowly falling forward thus rendering the seatbelt useless, this stresses me out as i dangerously seem to drive spending far too much time looking in my mirror at her to check she hasn't fallen forward, this never used to happen. i went into halfords today but the young worker there just seemed to look at me with mouth wide open and didn' know what planet i was on. cheers
