Interesting article and it is a coincidence in my life. My wife is pregnant and has been diagnosed with Group B strep and the dr has said she will be given Ampicillin during labor. I have some concerns regarding this, and now I read this article.<p>Dr says that there is 1 in 1000 chances of the baby getting (very) sick. With the antibiotics the chances are 1 in 4000.<p>I am wondering if anyone here has had experience with this.
