A mother who suffered post-natal depression and admitted killing her two young children walked free from court yesterday.
Felicia Boots, 35, pleaded guilty to the manslaughter of 10-week-old Mason and his 14-month-old sister Lily on May 9 on the grounds of diminished responsibility.
Her plea was accepted by the prosecution and charges were dropped.
In a statement read out by her lawyer, Felicia said: "The 9th of May 2012 is a day I will be eternally sorry for.
"It should never have happened and it troubles me more deeply than anyone will ever know. A part of me will always be missing. But I am a good mum and I never meant this to happen."
Felicia, who trained as a hairdresser, was ordered to be detained at a psychiatric hospital. She and her investment banker husband Jeff moved to the UK in the last few years from Canada.
He found the children dead when he arrived home at the couple's house in Wandsworth, London, an area known as "Nappy Valley" because of the number of young families living there.
Edward Brown QC, prosecuting, told the court: "This plainly is a tragic case."
He said the Crown had closely examined the medical evidence and spoken to Felicia's husband, who was in court today.
He added: "The authors of the reports are clear and agreed in their conclusions as to Boots's condition as at May 9 and the reasons for her actions on that day.
"As a result the Crown has taken the firm view that it is not in the public interest to pursue the counts of murder but to accept the pleas as entered."
