Hello.I am a midwife helping an Amish couple planning a home birth in the fall. Their second child was diagnosed with CF when she was six months old. They are aware that they have a 25% chance of having another child with CF.As their caregiver, I am curious about the possibility of a "mucous plug" that CF fetuses can develop. Apparently, sometimes they can be detected by a prenatal Level II ultrasound. Can anyone direct me as to where to get more information regarding this and any other info that I should be aware of that may be a risk to the newborn.Thank you all so much,Sylvia
