Hi, I am new on the site and I am hoping that someone can give me some ideas of how to manage my dd. She is 3.5 yrs old, and normally very sweet, thoughtful, kind, playful little girl. About once a day she turns into a monster, kicking, hitting and screaming at me. It usually lasts for 30 mins, sometimes longer. Then it just subsides. I have tried many many things. I do not believe in smacking so that is probably the only thing I have not tried. She doesn't do it to anyone else, just me. I would love to know any ideas of why it might be happening, and how I can manage it.
