Are you sending your child off to school with a backpack that is too heavy?
When buying one, make sure it is the right size for a child. Keep in mind, proportion.
Look for padded shoulders and different pockets to separate the weight.
The American Physical Therapy Association recommends a backpack should be 10 to 15 percent of a child's weight.
A backpack that is too heavy can injure a child.
The most common injuries occur in the shoulder because heavy straps can tear the tendons in the area.
If the child is leaning forward, that's a sign the backpack is too heavy.
