It's emerged that the Western Health Trust is to carry out a formal review of the treatment and care of a baby who died from pseudomonas in Derry.
Caolan Burke died from the infection at Altnagelvin Hospital when he was 10 days old.
In a letter to the baby's parents, the Western Health Trust said it has now decided to carry out its own formal review from the time of his premature delivery until he passed away.
The BBC is reporting this morning that the doctors involved in the case have also requested that clinical notes should be examined.
However, the family's solicitor, Walter Hegarty, said it was strange that the independent inquiry was not enough.
Gavin Burke and his partner Caoimhe Campbell held a formal meeting with Professor Troop and her team in Derry yesterday, saying afterwards she didn't appear to know about the trust's separate review.
In total, four babies died during the outbreak of pseudomonas in Northern Ireland in December and January.
The three other babies died at the Royal Jubilee Maternity Unit in Belfast.
