Elizabeth Pantley is one that I will recommend for parents who want simple, direct books with tips and tricks to help their child be happier.
Although I have not had time to read all six books I have been pleased with what I have seen thus far. My favorite thing about these books is that they encourage you to keep track of what your child is already doing with charts and quizzes and then use what they do to help them do what you need them to. Although I do not agree with every suggestion that is made in these books, but then who does agree with someone else 100%, I do like a lot of the strategies Elizabeth suggests.
If you are looking for some great suggestions and ideas in any of these six topics I recommend checking out Elizabeth's books. And make sure to head over to win during Oh Baby Baby.
