Why is my hair falling out?!

So I know that I am a wife and a mother, and that in and of itself could probably explain why my hair is falling out. But really...my hair is falling out like never before! There is no telling how much hair I have lost. It all started about 3 months post-partum. I know it is my hormones, as I lost some with Ceilidh as well; but not this much! Sorry if this is all a bit TMI for you, but I need to release my frustration. I am not in fear of losing my hair. Have you seen the amount of hair I have in this mop? It simply is an issue of annoyance. I find hair EVERYWHERE!!! The floor, on the hairbrush, in the shower, on my clothes, on my children, in the car, etc. UGH! Oh well, I guess it will have to stop at some point. Hopefully! ha Just a few pictures from the last couple of weeks.
