The High Court in Christchurch has heard Lauren Dickason relied on her husband to help manage her depression and anxiety.
But the couple's relationship changed when they had children, contributing to a decline in Lauren Dickason's mental state.
She is on trial for the murder of her three young daughters in Timaru in 2021 - but she denies the charges, instead seeking a verdict of insanity and infanticide.
Niva Chittock was in court.
