WHEN CHILD IS PLACED IN SEAT, THE FRONT RIGHT SIDE STRAP IS THE FASTENING DEVICE TO TIGHTEN BELTS. LIKE A NORMAL STRAP FASTENER, THERE IS A MECHANISM THAT LOOSENS WHEN YOU PUSH THE BUTTON, ALLOWING THE BELT TO BE MOVED EITHER DIRECTION. MY PROBLEMS ARE 1. MY CHILD WILL SOMETIMES ATTEMPT TO SLOUCH OR RECLINE BY SCOOTING HIS R HIP FORWARD AND TO THE R WHICH THEN PULLS ON SHOULDER BELT JUST ENOUGH TO ALLOW L SIDE TO TIGHTEN AN EQUIVALENT AMOUNT WHICH LEAVES MY KID SCREAMING MAD AND STUCK SIDEWAYS IN SEAT. 2. MY CHILD IS 2.5 YRS OLD AND 38LBS, WELL WITHIN THE 20-100LB WEIGHT SPECS FOR THIS CAR SEAT, AND HE IS STILL PHASING OUT OF THE TEETHING/MOUTH STAGE WHERE HE EXPLORES THINGS BY PUTTING INTO HIS MOUTH. WITH THE FRONT HARNESS BUCKLE STRAP BEING RIGHT UNDER HIS CHIN, HE NEARLY SUFFOCATES HIMSELF ROUTINELY BY SIMPLY PUTTING EXCESS STRAP IN MOUTH. HE WILL FURTHER GROW INTO CARSEAT MAKING CUTTING AN UNREASONABLE OPTION. BUT EVERY TIME I TURN AROUND I FIND HIMSELF GAGGING ON THE EXCESS STRAP (ABOUT 5" ). HE HAS CHOKED AND VOMITTED 2 TIMES NOW AND I REFUSE TO PUT HIM IN SEAT ANY MORE. *TR
