You are right to be concerned about your daughter's behavior. Catching difficulties early and taking steps to make changes is very important. Your daughter is young and just starting school. You and she have a great opportunity to change for the better. While there are some excellent parenting books and workbooks out there, I really encourage you to get in a parenting class or group. Many schools offer such classes or family support centers offer such classes. The big advantage is that you can talk to other parents. You will gain so much from hearing about other parent's difficulties and the solutions that they find. You may be able to find parenting classes/groups through United Way. Call 2-1-1 or go their website, www.211.org. Both are information and referral sources. Here are a couple of good books -
"Active Parenting Now: For Parents of Children Ages 5 to 12" by Michael Popkin
"Parenting with Love and Logic" This is published by the Love and Logic Institute, check out their website - www.loveanlogic.com
"The Parents Handbook: Systematic Training for Effective Parenting" by Don Dinkmeyer
Good luck to you and your daughter.
