Heavy school backpacks strain kids' bodies: expert tips to lighten the load

Heavy school backpacks can strain children's bodies, and experts advise parents to keep loads as light as possible and watch for difficulty walking or leaning forward. The American Academy of Pediatrics notes back injuries are uncommon but possible. Guidelines suggest 10-15% of body weight, but experts say individual factors matter. Choosing padded, fitted backpacks and teaching safe lifting help. Teachers recommend auditing daily necessities and cleaning bags weekly. Kids should remove backpacks in vehicles, as wearing them can interfere with seat belts.
