Nanny says Lindsay Clancy appeared to be a loving mother before killing her 3 children

Lindsay Clancy's former nanny testified at her murder trial that Clancy appeared to be a loving mother to her three children before they were killed. The defense argues Clancy suffered from postpartum psychosis, while prosecutors claim she acted intentionally. The nanny described Clancy as attentive to her children's needs but noted she was losing weight and struggling with sleep.
