I did take my 2 children, ages 6 months at the time and 7 years, with me on 2 cruises in May, when swine flu was first being reported. My kids were fine. I'm also not one to panic, but I am VERY germophobic. I'm a healthcare worker and hand hygiene is something that I do habitually, and have taught my older son and dh. Just teach the kids to wash, wash, wash and keep lots of hand sanitizer with you. WE had our own bottles in the stroller, diaper bag, etc. and used the ships' hand stations constantly. If the kids wash their hands before eating, it will cut down on the incidence of illness. Good luck!
