Should a child a family history of arthritis use a rolling backpack or a carrying backpack?

Backpack: I recommend a rolling backpack. Kids carry too much weight now in their packs which can cause back pain.

Whatever they like: An unaffected kid should be permitted to use whatever type of back pack they are capable & interested in using. Pushing them to avoid exertion because they might develop an illness later on is a sure way to promote a sedentary, fearful lifestyle.No one benefits from negative thought.
