Depends on the work, during work, the child's age, etc..
It is good offspring (or offspring) still be used with various small jobs, or rather: chores, duties. We can learn from the experience of others. And saw quite clearly that where children were razgaiati, held down, they are
not able to fend for themselves, plus they have a misconception about work.
Very good is that since small children in the house to perform specific duties or household. Those little things wrought by them to be rewarded with things that makes them happy: candy, toy, cartoon, etc..
