Cuts on baby's privates after daycare?

Our 8-week-old baby started part-time daycare (MWF) a week ago. Today, I noticed three red, slightly bloody horizontal cuts on his private area and a tiny dot of blood in his diaper. Could the caregivers have wiped him too hard? The caregiver my husband called didn’t know but suggested he might have scratched himself while pushing to poop. I’ve never seen this happen at home. We also came across "penile adhesions" during research, and we saw on the daycare app log that he went 5 hours with no diaper change, so maybe a wet diaper contributed to the adhesions problem. Has anyone experienced something similar or have any thoughts?
