I totally agree with Purplebutterfly and Nightbird .... I suffered with post natal depression twice ..very badly... your wife sounds like she is most definitely suffering with this .... my advice would also be to reconsider having another child right now .....

I wish you both well and sincerely hope your wife feels better soon. It is such an awful illness, but therapy and meds will help .... hugs and care, Jinnyann xoxoxoxoxo
