Your child left his backpack on the bus—again. Or he forgot to turn in his homework—again. Chances are, he’s been stricken with a common childhood malady: carelessness. It’s important to help him overcome careless habits now before they turn into irresponsible behavior as he gets older. Here are some tips: • Make it easier for him to remember. Is his book report due on the 12th? Have him mark it on the calendar in red. • Develop “anti-forgetfulness” routines. His nightly routine might include checking the calendar after dinner and making a checklist for the next day. • Don’t bail him out. If he gets a zero on an assignment because he left it at home, it may remind him to read his checklist.
