According to section RSA 265:107-a of the New Hampshire Law, all children passengers in a car younger than seven, or less than fifty-seven inches tall, must be secured using an approved restraint system.

In addition, all children younger than eighteen must be secured with a safety belt.

Suggestions are to keep your child rear-facing until at least two since this restraint system is the safest.

2. New Hampshire Forward-facing Restraint System Law

You should switch to the front-facing seat only when your little one officially exceeds the rear-facing system’s size limits.

This mostly happens around the age of two, but the official recommendations are to postpone it until the age of four, if possible.

Now, keep your child in this harness seat until the age of six or seven, or until he/she outgrows it.
