Hair Breakage?

I have a fair complexion, blond hair and blue eyes. When I was younger my hair was thin, and very straight. Around 14 years old, my hair became thicker, and finally very curly. I am now in my late 20's and I had my first baby in January 07. During the pregnancy, my hair didn't fall out very much, and became super thick and curly. About 5 months after the baby was born, my hair started to fall out at a very fast rate. I wasn't worried because my hair is so thick. Well, now I am concerned. My hair is pretty much all one length, but now my hair is breaking around the bang area, and it is looking rather strange. I can't pull my hair up anymore, because I get little wisps of hair sticking out everywhere. Is there anything I can do to stop the breakage? We are going to have a family portrait done soon, and I am really embarred about my hair! (I am still feeding too.) I use moisturizing products on my hair, and I sometimes straighten my hair with a flat iron. Thanks!
