Hair falling out

Jessica
I just had a baby 3 months ago. My hair is falling out really bad. When I brush my hair or run my fingers through it a lot comes out more than it use to. Is this normal or should i be worried. I have been stressing out a little bit so I'm not sure if that's the reason. Does anyone have any ideas of why my hairs falling out or has experienced this an what did you do to help it?
