Children and bag weights
 The bag should not weigh more than 10% of
the childs’ weight.
 Thus a 50kg child should only carry 5kgs
maximum!
 The bag weight needs to be against the
spine, and not hanging from the spine.

Time tables and subjects
 Most timetables allow for 5 – 6 subjects per
day.
 Thus a child has to carry for 5 – 6 subjects
every day.
 Each teacher insists that all the books for that
subject are at class……. Let us see what that
means for the child’s back!

In a nutshell……..
 Most children are carrying 3 – 30 % more
than is healthy for them.
 The long term effects will only be felt when
they have left school!
 Even the best bag in the world needs
parents, teachers and schools to help solve
this issue.
The solution!
 Parents need to contribute.
 Teachers need to contribute
 Children need to do their bit too!
Teachers/Schools
 Install lockers, in a convenient place for the children to
access between lessons. It should not take more than 2 minutes for
the child to reach the locker.
 Teach the children how to use the lockers. Take only the
books you need until the next break.
 Allow time for the children to use the locker.
 Use thinner books. Why make them carry a 288pg? Use 72 or 96 pg,
and bring a new book when the first one is full!
 Plan your week and share this plan with the children. Do
not change the plan on the day so that the children are in
trouble for not having their books there! If you say you are
doing literature on Weds, then do literature on Weds. Then all the children
need only bring literature books, saving a lot of weight on their backs.
Parents
 Buy the best bag you can afford.
It should have
an internal frame to keep the weight of the books against the
spine, and not hanging from the spine. This also protects the
books!
 Encourage/teach your child to use the
lockers.
 Encourage/teach your child to unpack and
repack everyday so as not to carry
unnecessary books and clutter with them.
 Speak to your school to use thinner books,
install lockers etc.
Children
 Unpack and repack your bag daily.
 Carry your bag using BOTH shoulder straps.
 Speak to your teachers if you are carrying too
many books, to find a solution.
 Use your locker effectively. Take only as
many books as you need until your next
break!
