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

Before Lindsay Clancy strangled her three children, she couldn’t sleep and complained of mental health issues, the family’s former nanny testified.

Months before Lindsay Clancy strangled her three children, she lost significant weight, couldn’t sleep and complained of postpregnancy mental health issues, the family’s former nanny testified at her murder trial Wednesday.

But the nanny never worried the Massachusetts mother might be a danger to her children or to herself.

“I observed a wonderful mom who loved her kids,” Elaine Rossi told the jury on the seventh day of the trial in Plymouth. “She was concerned about their safety, and Callan eating and sleeping. She was a wonderful mother.”

Clancy’s defense says she was a loving mother who was overmastered by postpartum psychosis, a dangerous psychiatric condition that afflicts a small proportion of women after childbirth and affects their hold on reality.
