and how long you can work under this condition. It caused my son's asthma too. I had sent notes to daycare about this. when daycare use bleach to clean room, kids should not be in room according to regulate. But no daycare care about if kids is in room or not, they even spray right too the kids. I had watched the teachers did this and this is why I sent the note to teachers. good thing was that teacher also has asthma.
