A woman accused of murdering toddler Liam Fee has told her trial of concerns she had over changes in the two-year-old's development.

Nyomi Fee, 28, said she found it “upsetting” to see the boy “harm” himself and not know what could be done to stop it.

Fee is on trial for a sixth week at the High Court in Livingston alongside her civil partner Rachel Trelfa, or Fee, who is 31.

Both Fee and Trelfa – Liam’s mother – deny murdering the toddler, who died at a house in Fife on 22 March, 2014, and falsely blaming his death on another boy.

The pair, originally from Ryton, Tyne and Wear, also pleaded not guilty to a string of allegations of wilfully ill-treating and neglecting two young boys over a period of more than two years.

Fee is the first witness to give evidence for the defence after the Crown closed the prosecution case on Friday.
