Kids who carry backpacks that are too heavy risk having back, neck and shoulder problems in the long run. According to the experts, backpacks should not weigh more than %15 of your child’s body weight. Kids who carry heavy backkpacks tend to lean forward to balance themselves and this puts a lot of stress on their backs and necks. In the long term, the spine loses its shock absorbing properties.
If the backpack is carried using only the strap, the child might end up leaning to one side to make up for the extra weight. A good backpack for kids should have wide, padded straps that fit over the child’s shoulders, padded waist or chest belt that distributes the weight of the pack and a width not greater than the child’s chest. Internal frame backpacks like the ones used by hikers are great for children but might not fit the school locker.
