Hi A.,
Watching Supernanny on TV has helped my husband and I a lot. You might consider watching a few episodes. Also, the Johnson County Library has a book of hers. Here's some info. copied and pasted from their site.
Happy Parenting,

Supernanny : how to get the best from your children
Frost, Jo.
Summary
Jo Frost, a.k.a. SuperNanny, is the answer to every stressed-out parent's dreams. In Abc's upcoming primetime tv series by the same name, Jo works miracles on problem children by dispensing hard-won wisdom and reassuring us that parents really do know best. The SuperNanny method gives parents the know-how to tackle problem areas such as mealtime, bath time, bedtime, bedwetting, homework, sibling rivalry, aggressive behavior, or a child who just won't do what he or she is told to do. Divided into action-oriented problem and solution sections, SuperNanny will show parents how to restore harmony and authority in the home using the SuperNanny's ten basic rules.
