I would say they take advantage because you let them .... When one of my kids is away sick I always text in the eveni g to see how the child is doing and if they waiver at all them I tell them to stay home.... But I will admit that one day a parent walked in with her child and handed me over the counter eye drops and said please put these in his eyes before nap as last night he started to cry and all thus green gunk came out of his eyes .....so I should have handed her back the drops and the child and said see ya tomorrow ... Buuut.... I didn't .... And I was so mad at myself all day and when she picked up I told her next time please keep him at home as I don't want all the other kids possibly getting it .... She said the dr said it wasn't contagious so that's why I brought him ....I hear where your coming from as I also had my first three kids in daycare and couldn't take a lot of time off but sometimes you have too, it's part of being a working parent.
