Ms Taylor told the inquiry she had never heard of going back to the unit where a death occurred as way of dealing with or getting over trauma.
When asked what she thought about Letby wanting to go back to the nursery where the baby had died, Ms Taylor said it was “highly inappropriate”, adding: “The text messages I’ve seen show a lack of compassion.”
Ms Taylor told the inquiry she did not have any suspicions at the time that Letby could be harming babies.
“That’s an unthinkable thing in a way.
“Nursing is a profession where you put your trust in each other, and I mean this is not an event that happens in anybody’s lifetime.”
Letby, 34, from Hereford, is serving 15 whole-life orders after being convicted of murdering seven infants and attempting to murder seven others, with two attempts on one of her victims, between June 2015 and June 2016.
The inquiry is expected to sit until early next year, with findings published by late autumn 2025.
