7. Chart the day: Try keeping a daily or weekly schedule posted on your child's bedroom wall or stuck on the refrigerator with magnets, with spaces for writing activities. Take some time to sit down with your child to fill out the chart together, and talk about what's planned. Note regular routines, such as lunchtime or gymnastics class, including what your child needs to take with him, as well as special events such as birthday parties. You may want to use a notebook that your child can take to school. Ask your child's teacher if she'd be willing to fill in the log with school activities, including writing down daily homework assignments.
8. Stay positive. it's extremely important to address your child's behavior problems in encouraging terms. Try the 'sandwich approach,' also called the good/bad/good technique. For example, if you need to remind your child to follow directions, start out by offering him some good news: "You have a very special and wonderful way of seeing the world." Then bridge to what your child needs help with: "I noticed that you have trouble following directions and we're going to help you with that." Follow up with another positive: "I remember yesterday that you picked up your toys like I asked you to and I'm very proud of you."
9. Offer lots of praise. Many parents use reward charts where positive behaviors are visually recorded on a regular basis. A simple paper or poster board chart on the wall does the job. Note accomplishments — such as finishing homework or clearing a dirty dish — with a sticker or special mark on the chart. Some families devise reward systems where their child gets a special treat after accomplishing a certain number of small tasks.
