When I had my CAH son 9 years ago they were still arguing about whether or not they should automatically test for GBS.  I was on the losing end of that one.  I had lost my mucus plug (sorry) a week + before I went into labor so there was a lot of time for infection to develop.  On top of that, he was breech (which we wouldn’t find out until later) and as such, his head didn’t drop down to block the hole where my water broke.  Needless to say, every hour it was like my water broke all over again.  The trip to the hospital was almost comical with me wearing a huge draw string skirt and sitting on beach towels with a garbage bag underneath all that (my sweet husband thought of that one).

I ended up having to have an emergency C-section and my son DID contract Group B Strep. The doctors told us that even with a C- section, anytime the membrane is broken the infection can enter the placenta and, IF the baby somehow ingests some of the fluid, the risk is increased that that baby will contract GBS.  Since we were unaware that CAH was even a consideration at that time, the hospital staff couldn’t figure out why he was crashing so badly and they couldn’t turn him around.  The third or fourth day in they called to tell us that it didn’t look like he was going to make it through the night.  He did and began to fight for his life and only God knows how he survived until at two weeks+/- he tested positive for CAH and they then began to treat him with the proper meds.  And on day 28, we brought our beautiful and healthy baby home.

They now test for GBS automatically AND, with the stoic work of two women in CT and a copy of my son’s delivery bill ($150,000+) they changed the ruling and CT is now testing for CAH!!!!See, good things can come out of bad.  If we had not contracted GBS and we brought him home thinking he was a "normal" healthy baby, we don’t know if we would have realized that he had a problem until it was too late.

I would speak to your doctor about your concerns and  get the antibiotics even with a C-section.

You are ahead of the game Elizabeth.  You already know that you have GBS  AND you already know that CAH is an issue.  You and your baby should be fine.  I don’t want to sound like an alarmist, but you should always err on the side of caution as there are no do-overs in childbirthing.

We will keep you in our prayers.

P.S.  Everyone should also keep an eye out for RSV with a newborn and especially a newborn with CAH.
