Verphy Kudi, 19, was jailed for nine years at Lewes Crown Court last week, after admitting to the manslaughter of 20-month-old Asiah in December 2019.
The court heard that Kudi left her daughter alone in their Brighton flat for six days while she celebrated her 18th birthday at parties in London and Coventry.
Asiah was taken to hospital by ambulance on 11 December after her mother called 999 saying she was “unresponsive” but she was pronounced dead on arrival.
The results of a postmortem and forensic tests found that Asiah died from neglect.
Kudi initially claimed to have left her flat just once over the six days to travel to London with her boyfriend but pleaded guilty to manslaughter at a hearing in March.
The teenager suffered from post traumatic stress disorder (PTSD) after witnessing domestic abuse as a child and becoming a victim of child sexual exploitation, the court heard.
Kudi became known to Brighton and Hove children’s services aged 15 after her mother reported her missing a number of times.
After going missing for five weeks, Kudi was placed in accommodation in Norfolk but fell pregnant after six months in the placement.
Asiah was placed on a child protection plan from birth but this was later removed meaning neither she nor her mother was in the care of a social worker at the time of her death.
A spokesperson for the BHSCP said: “We are deeply saddened by the tragic death of Asiah.
“In our safeguarding role, we are currently working with our partners to look into what happened and are conducting a child safeguarding practice review.
“We aim to publish the review report in the autumn.”
Detective chief inspector Andy Wolstenholme, from Sussex Police, said: "This was a particularly distressing case for my team and me to investigate, and has caused great sorrow amongst Verphy's family and the many agencies that have supported Verphy and Asiah.
"In pleading guilty, Ms Kudi accepted the terrible judgments she made in leaving her child alone and unprotected for such a protracted period, and accepts the lies she told to friends, family and professionals to cover up her neglect of her daughter and in order to avoid being caught.
"I hope Verphy's acceptance will help the rest of her family to grieve the terrible loss of Asiah. Sussex Police will always go the extra mile to investigate offending against children and all vulnerable people, as well as supporting their families and friends. I would always urge anyone who has concerns for the wellbeing of a child, or vulnerable adult, to contact the relevant authorities as early as possible, so that supportive interventions can be made."
In a statement, Asiah and Kudi’s family added: "We are saddened by the current situation and as a family we have many unanswered questions. Verphy has experienced so much at such a young age and we have always done what we can to support her.
"As a family we are in the midst of an unbearable tragedy. Not only are we coming to terms with what has happened today but we are also still grieving for our beloved Asiah. We would be grateful if our privacy can be respected at this moment.”
