Nurse Gloria Dwomoh has been jailed for three years at the Old Bailey for killing her baby by force-feeding her in the first case of its kind in Britain.
She was found guilty at the Old Bailey last month of causing or allowing the death of 10-month-old Diamond.
The nurse was said to be obsessed with Diamond's weight and poured liquidised food down her throat with a jug when she was weaning her.
Diamond died in March last year after being taken to a hospital near her home in Waltham Forest, east London.
A post-mortem examination found she died from pneumonia caused by food, including meat and cereals, in her lungs.
Now, an investigation is being launched into feeding methods used by mothers, particularly those from cultures where bigger babies are considered to be healthier.
A serious case review reported 18 key findings, including the lack of understanding on the issues which should have caused alarm bells to ring.
