I'm actually responding to the more general feeling you conveyed in your "A little about me" section, where you wrote, "I love being a mom but I do get upset and feel hopeless, my daughter is very strong willed!!!"
I've been doing some research into positive discipline, and Becky Bailey's book, Easy to Love, Difficult to Discipline made a lot of sense to me. I checked it out from the library and I see children, discipline, and conflict in general in a whole new light! I have practiced some of her principals on my interactions with my husband (like starting off thinking about where he's coming from, and using her tools for figuring out where he's coming from, and communicating what I want), and they have made our relationship a lot more harmonious. And all it took was just a little bit of the right knowledge!
Bailey talks about common discipline issues like going to bed, picking up after oneself, tantrums, hitting other kids, etc.
Really. Save yourself a lot of head- and heartache. Check it out!
