GBS is very common and is in the digestive tract of most people. The problems occur when there are germs on the rectal area, and the medical staff checks the mom, she can become colonized vaginally, and it *could* cause an infection in the baby. But you can do a perineal wash with Hibiclens liquid soap, available at any local pharmacy: Walgreens, RiteAid, what have you. You make a solution and squirt it on your bottom during labor, and that takes care of it. Kills the germs on contact. No need of abx. If you do a google search for GBS wash you will find several recipes....PM me if you can't find it and I will give you mine....
