I left a handout at school which mentions effective methods in clearing out the clutter from your children's lives, starting with the toys. You can also use these techniques with their clothing. Please let me know if you need more information on this topic.
Payne believes if you provide your child with lots of time for free play and down time, many of your disciplinary issues will decrease.
