I agree that training is key - I have never had an issue with anyone doing this to me - my clients are awesome of when in doubt calling me to ASK if they should stay home or not before getting here - I am generally flexible and empathetic in return on "trying" of they are fever free but just not themselves but no symptoms to see if they will cope in program and in return find that clients tend to keep their children home when REALLY needed without me pushing for it and often keep em home when I would have taken them ... had a client my first year who called her child in "bitchy" on quite a few occasions - aka teething and not herself but what was bitchy to her mother was most kids NORMAL cause the child was an angel normally and never cried or whined or misbehaved
