K.S.
We were just talking about the pertussis outbreak in CA at work today...
My first thought was talk to your own doctor about you and your husband's immunity to see if you would benefit from a booster. Your baby needs you both to stay healthy now.
My next thought was breastfeeding but see with the reflex that may be hard. Stick with it and/or pumping! Every drop that gets down and stays down will help.
Stick a little closer to home. Remember that washing hands is one of the single best ways to stop the spread most infectious diseases. Have a just-say-no approach to visitors until your child is in the clear.
My final thought is when you get through this (you and baby WILL get through this) be a vocal advocate for vaccines. It seems hard to argue against the thought that other parents' choices NOT to vaccinate put your vulnerable newborn at risk. My thoughts are with you and your baby.
