Hi there. The various signs and symptoms of postnatal depression are lack of interest in the baby, negative feelings towards it, lack of self concern, lack of energy and motivation, change in appetite and weight, sleeping more or less than usual and recurrent thoughts of death or suicide. These changes are seen because of falling estrogen, progesterone and thyroid levels post natally. Consult a psychiatrist for psychotherapy, hormone therapy involving replacement of estrogen marriage counseling, and antidepressants if indicated. Hope this helps. Take care.
