Thanks for the replies. The incubation period is 10-21 days, so we're still in the "wait and see" phase. If she doesn't get it, I'll be very, very surprised. The kellymom.com website said that she isn't fully immune, but will likely have a milder version, due to my antibodies that were transferred in utero. Apparently the breastfeeding antibodies are different than the ones that get transferred prior to birth.
DD's 6 month immunizations were scheduled for next week, so I've rebooked them for the following week. No need to have immunizations colliding with the manifestation of the virus.
Your comments were very much appreciated. Thanks!
