The CARES Child Airplane Safety Harness has been designed specifically for children aged 1 and older, who weigh between 22 and 44 pounds. However most airlines allow children to remain on the lap until two years old, but at this age children can sit in their own seats if you choose to pay. The issue is that all the seats on the planes have seat belts that are designed for adults and don’t hold their little bodies in place as well. The CARES aims to help keep your child more secure during the flight.
