Parents can test whether a coat is too bulky using the method below:
• Have your kid wear the coat, sit them in the car seat and fasten the harness.
• Tighten it until you cannot use your thumb and forefinger to pinch the webbing together.
• Next, take your child out of the car seat and remove the jacket while keeping the harness at the same tightness level.
• Place them back in the seat.
• If you can pinch together the webbing now, the jacket is too bulky.
