Assuming that you are correct and this is post-partum depression, does the "pathologic chemical imbalance" that we assume she had also keep her from recognizing that something was wrong with her? Did it keep her from seeking help? I know several women who became depressed (to varying degrees and due to various causes) and then sought help. This woman has no excuse. She chose to kill.

Yes is the short answer, it's entirely possible she had no insight into her distorted thinking.
