When Sophie Archer, 22, left for a three day trip to New York for her 21st birthday last March, she thought she was leaving her 23-month-old daughter Roxie in good hands.
But 24 hours into the holiday Sophie received a call from her boyfriend Ben Raftery, 21, telling her that Roxie had accidentally fallen down the stairs and had suffered fatal head injuries. She died in hospital a day later.
Ben was arrested on suspicion of murder, and was jailed for life after covering up the true extent of Roxie's death. Sophie says she blames herself, and can never make up for her daughter's death.
