This all wrong. Rear facing til 3 years old. Then forward facing in a 5point harness till they out grow it. Our son is 7 and a half and only now moving into a full back booster seat what he will stay in till he is 12 to 13 years old. A 9 year old just died in South Africa from being in a car accident (head on collision), she was just strapped in with the seat belt. Do not rush out off the booster!
