Kids at home are used to be treated as child, which they really are. But if children are in their developing stage, values must be inculcated in their young minds. Especially for those who are about to start in going to school.
Values are just like food, if a child gets used to ingest only those which they want, they will grow not wanting or even trying what is good for them.
It is not so hard to train a child for as long as they can do it for fun. Parent should allow the kids to participate in some chores at home. They could motivate the child to sleep early as a start by telling them that they will be accompanied in buying the groceries the next day. Let them participate in preparing food would also encouraged them to be experimental and let them see and appreciate for themselves the outcome of what they did.
If they become used of the routine, when the time of sending them to school comes. it would be of ease for both parents and school authorities to motivate the child to be organized and responsible. It is also easy for the child to learn and absorb the teachings during their development stage.
