My baby girl is just over 4-weeks old. Since she was born, my wife has been more than a little weird. She cries for no reason. Yesterday, I told her that I was going to go to the local high school football game tonight and she got all pissed off. She actually got to the point that out of the blue she said "If you don't want to be here...move out...I don't care". Keep in mind, other than the stress of having a newborn, our relationship has been just fine recently. Is this possibly an example of post partum depression? How long does this craziness last? Lately, its seemed like everything has been my fault.
