When can a child transition to a forward-facing car seat with a harness?

The transition to a forward-facing car seat with a harness is ideally recommended when a child turns 2 years old or has outgrown their rear-facing car seat, which means they can no longer fit comfortably or safely in that seat. This guidance is based on substantial research showing that children are significantly safer in rear-facing seats until at least the age of 2, as the rear-facing position better supports their head, neck, and spine in the event of a collision.

While option A suggests transitioning as soon as a child turns 1 year old, this does not take into account the child's growth and development, which is why merely reaching the first birthday is not sufficient for making the switch. Option C, focusing on the child's ability to sit up straight, does not provide a comprehensive guideline for safety, as children may be able to sit up straight but still not be ready for the additional forces experienced in a forward-facing seat. Lastly, option D sets a specific weight limit as criteria, which is less relevant compared to age and developmental milestones. It is essential to base this transition on a combination of age, size, and the specific limits of their current car seat, making the guidance provided in option B the most accurate for ensuring a child’s safety in
