Unbuckling the seatbelt is a dangerous habit, like crossing a street without looking both ways for oncoming vehicles. It is important to explain this to your child as a required rule and state law for riding in a car. There are children that are ‘rule-followers’ and would not want to violate this rule. There are also children that are risk-takers and challenge the rules. Either way, the child must understand that this is a rule/law that may not be broken. When all else fails, perhaps research a more difficult car seat or seatbelt for confinement.
