I just got off the phone with my rep and she says that if the parent or hospital file a report that they'll be out to investigate but based on my side of things it just doesn't add up. She said "take a deep breath and consider it a blessing that they brought their kids to you another day after the incident". Duh because if I abused their kid they surely wouldn't bring him back!
She also said that there's really no way that it would be red and raised only during the time she had him but before he left yesterday and this morning there's only a tiny scratch there.
She instructed me to fill out the incident form, attach my emails to/from licensing, and stick it in his file. And to document EVERYTHING! You ladies are so smart
I'm going to make a decision this afternoon after pick up on whether I keep trying with this family or not.
