One week into preschool, LO has come down with a cold- sniffles, running nose, slight fever (99). She's otherwise playing/acting normal. I think she gave it to me, too, bc now I feel all congested and crappy too

At what point do I keep her from preschool? I'm thinking that if I kept her out for each cold/runny nose, she would never get to go :T I don't want to be that inconsiderate mom that sends her sick kid off to infect everyone, though.
