After being at LGH for a few weeks, Melissa said Milo was “really showing signs of being unwell”.

Milo had X-rays and a sepsis screening, which came back clear.

However, at a staff handover on 25 May, she heard nurses saying they had only just disposed of breast milk which had been defrosted more than 72 hours earlier.

The NHS recommends, external defrosted breast milk is used immediately.

Melissa said: “I stormed down to the doctor that had done the screenings and X-rays and asked if that was causing his symptoms, to which he said ‘I can’t say yes and I can’t say no’, which gives me enough of an answer; I believe this breast milk had been used the night before.”

UHL said it was carrying out a wider review of how breast milk is handled, as a result of Milo’s care.

After being transferred to the Queen’s Medical Centre (QMC) in Nottingham for further treatment, Milo was eventually discharged on 7 July.
