It would be a good idea to talk to the parent of your daughter's friend, as well as find out what your dh cultures. B.cepacia is not the only bug of concern when it comes to cf. If one of them is colonized with mrsa, for example, that is a concern... and if the child is not yet colonized with PA (as an adult, it's probably almost a given your husband is), a casual stance about the 3ft rule may not be enough. Households where multiple people with cf live together are one thing, avoiding voluntary contact is a different situation altogether. I'm sure there are plenty of ways to get the girls together safely without introducing the risks of cross-contamination... wishing the best! <img src="i/expressions/face-icon-small-smile.gif" border="0">
