I am almost certain that a particular child is bringing fleas into the setting from home.Child has many pets and attends our setting Thursday and Friday. We go all week fine, then the end of the week, guaranteed for the past 2 months, flea bites on me, my lo and so far two other visitors. I don't know what to say or do. Child doesn't have any bites, we don't tend to do any different activities outdoors towards the end of the week, I've caught several so I know its definitely fleas. We have no pets. I'm concerned that another child will go home with flea bites and I'd feel terrible. What can I do?!
