I can totally relate to this as we are going through this with our child this year as well. We were told by the school to NOT treat it as a "secret" because we don't want our child to feel it is something to be embarrassed about, but also to feel free to not bring it up unless someone else does, basically to just follow our own comfort level. At the school's suggestion, our child did tell a few friends and it seems to be getting around quietly that way. So far, so good, but we did already get two strange phone calls from different parents calling for obviously pretextual reasons, who then asked for info, so be on the look out for that. Good luck!
