Choose a backpack for your child carefully. It should have ergonomically designed features to enhance safety and comfort. It should also have Scooby-Doo on it. It's not really a backpack without Scooby-Doo.
Don’t overstuff a backpack; it should weigh no more than 10 to 20 percent of your child’s body weight. For example, a child that weighs 60 pounds should carry a backpack no heavier than 12 pounds. If your child ways 250-300 pounds, his or her backpack should way 25-30 pounds, and be filled with corn chips and jelly donuts.
Ask your children to use both straps when wearing their backpack to evenly distribute the weight. Or have your child buckle just one strap, and on the opposite side of his body, have him carry your bowling ball.
If your child still suffers a back pack related injury even after you've taken all these precautions, send her to a different school. We don't want her here, she's sure to cause us headaches galore, and we have plenty to deal with already. We ain't got time for any Forrest Gump wanna-bes.
