Use a sling keeps babies nice and close like a carrier. I wouldn't get too freaky about people touching kids if they aren't hacking or just walking out of the bathroom. I mean, as scary as it is, your kids are going to pick dirty things up off the floor, flush a toilet, climb on a restaurant seat, go to school, share toys... They are going to get germs. Keep some baby wipes or hand sanitizer with you if that makes you feel better. Teach them to wash their hands faithfully and not to put their hands in their mouth. Other than that, try to treat them the same way you would treat a child without CF. You still don't want someone with the plague smearing their hands all over. But, not every person is a grave danger to your child. Most of us adults were never told to be that careful, we almost all went to public school, very few of us were breastfed (which is probably the best thing you can do to prevent your child with CF catching things, btw) and we're all here. I'm not trying to be harsh, please don't take it that way - just realistic. You don't want your child to grow up having not only CF, but emotional/mental issues from being treated so differently also.
