A Canadian woman charged in the deaths of her two babies in the family's posh London, U.K., home was set to appear at South Western Magistrates Court on Saturday, London Metropolitan Police said.

Felicia Boots, 34, had been charged with two counts of murder, the UK Press Association said Friday.

Police said a post-mortem had been conducted, but a cause of death was not given.

Boots worked in Canada as a hairdresser before she and her husband, Jeff, 34, moved to the U.K.

Local media reports said Jeff returned home Wednesday evening to find the children -- a 10-week-old boy and his 14-month-old sister -- dead. Paramedics were unable to revive them.

There were also reports Felicia suffered superficial wounds to her wrists.

Neighbours told the Telegraph newspaper the couple had just moved into the home two weeks earlier. The $2 million home is in a popular neighbourhood for young families.

Felicia works out of a home-based studio as a jewelry designer under the business name Pink Tangerine.

The blog for her business includes testimonials from two Canadians who describe her as having a "carefree and outgoing attitude," and a "great spirit and a real magnetism."

On Thursday, Department of Foreign Affairs and International Trade spokesman Ian Trites told QMI Agency consular officials "are in contact with U.K. authorities concerning the death of two Canadian children and the detention of their Canadian mother."

Some media reports suggested Felicia may have been suffering from postpartum depression.
