Both happened when my ex sister-in-law called to tell me that my ex had died… our son had just started 2nd grade. He was standing right beside me, and I knew it was going to break his heart.
I have also had to inform parents that their child is hearing impaired or deaf, and while it isn’t as bad as diagnosing a terminal illness, it is still heartbreaking for the parents to learn that little their angel isn’t perfect.
I have also had to perform Brainstem Auditory Evoked Response testing on children to confirm brain death. Fortunately, it was not my job to inform the family, but it still was very hard for me to handle.
