As a parent we all want our children to be assertive but not aggressive toward others. The types of aggression are dealt with in an earlier post so right now I will share a few authors that have good stuff.
Joanna Faber and Julie King. How to talk so little kids will listen.
Aubrey Harris and Breana Sylvester. Toddler discipline for every age and stage.
Parenting a strong willed child
Marjorie Kostelnik, Anne Soderman, Alice Whiren and Michelle Rupiper. Guiding Children’s Social Development and Learning. This book is a college textbook but is an easy read and resource. I have given it out to many parents who are seeking first to understand and then to shape their children’s behavior.
