Other students simply use the wrong type of backpack or wear it incorrectly. When choosing a backpack for your child it is always important to keep safety in mind.

The American Academy of Pediatrics recommends parents purchase backpacks that are made of lightweight materials such as nylon or canvas and avoid leather, plastic and other heavy materials.

It also recommends backpacks have two, wide padded shoulder straps, a padded back, and a waist belt. Messenger bags that hang over one shoulder can strain muscles and may increase curvature of the spine.

Backpacks on wheels are great, but are difficult to pull up stairs and pose a tripping hazard in the hallways. Some schools have a policy against them, so check with the school to see if they are allowed.

Having the right backpack is only part of the solution. Children must also be taught the proper way to pack and wear their backpack.

Backpacks should be packed lightly and should not weigh more than 10 to 20 percent of your child’s body weight. For example, a child who weights 80 pounds should have a backpack that weighs no more than eight to 12 pounds.

To help distribute weight evenly, use all the backpack’s compartments; packing the heaviest items, such as textbooks, closest to the back. Tighten the straps so the backpack is close to the body and sits two inches above the waist.

To help lessen the load, check your child’s backpack and remove any unnecessary items such as ipods and toys, encouraging your child to only pack what is necessary.
