I know there was a thread about this recently, but I wanted to pose the question again : I have a dck who has croup and his little brother was still coming to daycare until today when I sent him home as he was starting to lose his voice (which was the first sign with his brother). Should I have asked the parents to keep both kids home in case? If he does have croup too, I will feel bad that I exposed the other kids to it again (the other brother already came down with it while at daycare so they have been exposed already). Doesn't help that when I called the mom, she was on her way to visit a friend...while leaving her sick baby with me Does anyone ask parents to keep siblings home when one sibling has something serious like croup?
