It is unfortunate that parents are not aware about the ill effects of excess weight
Growing children have tender spine which is not meant for weight lifting.so weight bearing for long duration can bend the back bone.it will result in backpain.
Shoulder bag can restrict breathing of your kid.so air entry in to the lung is reduced which may cause lung disease in future.
Other pains such as hand pain and leg pain can occur
Chronic weight bearing can damage the knee joint and will cause early onset of osteo arthritis of knee joint.
HOW TO DEAL :
it is recommended that children should not carry 15 % of their weight .that is if your kid is 15 kg ,he should not carry more than 2.25 kg.
